Remote: Yes (have worked exclusively remotely for past 14 years)
Willing to relocate: No
I've been doing backend work for the past 14 years, with Python, Django, and Django REST Framework. I'm intimately familiar with schema and data migrations, including migrations between Django projects. I've done a lot of full-stack work as well, with HTML, CSS, JavaScript/jQuery, and React.js. I've worked extensively with startups and I've worked with Twitter. I have a lot of experience working with distributed teams and am open to occasional travel. Available full (~32hrs) or part time. Interested in Python work or full-stack with Python.
10+ years production experience across healthcare, fintech, insurtech, ERP integration, and AI infrastructure. Currently co-founding Strikaris LLC and building MirrorOS: a tamper-evident audit ledger for AI agent decisions with formal verification via Prolog and Z3. Open to staff/senior engineering, platform, integrations, or AI infrastructure roles.
I'm graduating in a month, so I'm seeking junior/graduate-level roles that revolve around backend and systems development where I can learn a lot. My experience includes four internships and multiple side projects (please check my resume and GitHub).
I started programming on my own at the age of 15. Since then, I have explored multiple areas, including mobile app development (native and Flutter), web development (React, Next.js, Vue), QA, MLOps, and AI/ML. During this exploration phase, I realized that I want to focus my career on backend development.
Most of my coding experience is in Java and Python. I also really enjoy Kotlin and am currently learning Go (Golang) by building a simple VPN as a side project. However, I am not limited only to these languages.
Hi, i'm Samir. I'm a junior software engineer with a B.Sc. in Mathematics & Computer Science (Data Science). I recently completed a contract at an AI startup where I built data-intensive React UIs. I also developed REST API endpoints, implemented full authentication flow with WorkOS, automated end-to-end type safety between FastAPI backend and react frontend and added CI/CD pipelines on GitHub Actions. I've also worked on some side projects like a Job Tracker SaaS and a Legal AI RAG assistant. Looking for my next full-time opportunity in backend, full-stack, or AI-adjacent roles.

After building and selling a couple of companies, now I'm a quasi-retired "technologist" I guess. I like to build. The benefit is that I'm compensation-flexible and offer a straightforward style. Lately, I've been splitting my time building native apps and working on LLMs, but I'm very also comfortable in the middle of the stack and at the systems level. Somehow I wind up doing a lot of custom USB and BT work.
No drama. I don't want to run your company or lord over a tribe. The best fit is a situation where you need something done, you set the direction and constraints, then I bring you options to get it done and deliver it.

20+ years of experience. I'm a generalist who does a bit of everything which makes it difficult to decide what to list here. I love to work on things like developer experience (local dev environments, tools, CI/CD pipelines), upgrading/refactoring/rebuilding legacy applications, documentation, improving processes, and anything that lets me learn something new.
I'm mostly looking for side work, but may be open to full-time if it seems like an exceptional fit.
If there's anything your current team has been meaning to tackle, but hasn't had the time, feel free to reach out. I can work very autonomously with almost no onboarding.
Just about done finishing up a CS master's degree, and looking for opportunities starting in the late summer or fall. My background is in programming language theory (particularly logic/relational programming), so would be very happy to work with functional languages, compilers, automated reasoning, and/or formal verification. I also have a background in music (I'm a published composer!) so particularly interested in audio/music-related stuff as well. Open both to software enginering roles and research positions (anyone looking for new PhD/doctoral students?) I've also done full-stack work across databases/cloud infrastructure/web APIs/frontends, and independently released a commercial music production plugin (Pivotuner, more info on my website).
Senior Software Engineer with 8+ years of experience building scalable distributed systems using Golang and Node.js.
Specialized in microservices, event-driven architectures, and real-time data processing with Kafka on AWS. Proven track
record of improving system performance and reliability, reducing latency by up to 35%, and delivering production-grade
backend services.
Summary: Senior AI Full-Stack Engineer with 8+ years of experience building scalable, production-grade applications. Specialized in real-time AI systems, LLM-powered products, and low-latency backend services. Recently built voice-enabled AI assistants handling real-time transcription and automated clinical documentation for thousands of users. Strong background across full-stack development, cloud infrastructure, and modern AI tooling. Focused on delivering reliable, high-impact systems that solve real-world problems.
Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.
I am open to work for a company anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up a team for you.

Fellow Greenwich native here....though you're a bit older than me. My dad works with a number of hedge funds particularly those in the NYC area and the Miami area as a recruiter. Mind if I pass him your CV?
I've mostly been a first or founding engineer, owning systems that have to scale early. I focus on high-throughput pipelines, messaging systems, media transcoding, and recommendations—areas where issues show up under load, retries, and edge cases.
I also build real-time dashboards to observe and control these systems, using local-first approaches and browser-based technologies for media processing and realtime communication.
- Messaging systems delivering millions of emails and push notifications in minutes (retries, deliverability, observability)
- Browser-based video editing and encoding platform using FFmpeg, Supabase, and AWS
- Real-time pipelines and recommendation systems for tens of millions of users
- Scaled event ingestion ~100x for analytics and experimentation
I do my best work in small, product-focused teams, owning systems end-to-end, staying close to production, and communicating early around risks and tradeoffs.
- Founding or early engineering roles (full-time, part-time, or contract)
- Backend or infrastructure-heavy work
- Products with real users or a clear path to them
I'm Govind, a Senior Software Engineer with 15 years of experience building production systems across full-stack web, blockchain, and AI.

Hi, I'm Harry Altman! I was the maintainer of Truffle Debugger (https://github.com/ConsenSys-archive/truffle/tree/develop/pa...), a Solidity smart contract debugger, for 5 years. I eventually ended up writing my own decoding and encoding libraries to support it, as well as a bunch of other things.
I'm good at this sort of nitpicky work, spotting and thinking about edge cases. I like getting things exactly right, even though that obviously isn't always possible due to various constraints. I've been kind of wondering if I should get into embedded development; I find it appealing when things are low-level or similarly constrained. I've beaten Microcorruption. :) (The original levels, I haven't played the new ones.)
I'm also quite interested in unusual or obscure data formats, and working on Truffle Debugger and its associated libraries certainly involved a bunch of having to figure undocumented formats and interfaces. :) I put down above what languages I've worked substantially in but I'd say I'm a generalist and will figure out whatever you give me (I knew approximately no Javascript, Typescript, or Solidity when I started working at Consensys).
I'm a mathematician by background and in my spare time, so after the Truffle Debugger project was shut down I took some time off to focus on my mathematical projects, including old ones I've been shepherding through publication. But now I'm looking for work again! If you need someone like me, I'm available for hire!

SEEKING FREELANCE/CONTRACT WORK — I build production software for founders and growing teams. Full-stack engineering across Rails, Vue, and React, with AI-augmented workflows. 25 years of shipping, leading teams, and owning technical direction.
I spent a decade as CTO at EMEX, growing the engineering team from scratch through private equity acquisition. Today I operate through Brightform Technology, working with founders who need senior-level engineering without a full-time hire. The kind of problems where product sense and architectural judgment matter as much as code output.
Past work:
* Led all frontend architecture for an IoT platform processing high-volume sensor data across nationwide deployments. Built real-time building floorplan visualization, time-series HVAC dashboards, and a modular device configuration system.
* First engineering hire → CTO at EMEX. Built the flagship real-time reverse auction platform that drove seven-figure annual sales. Grew and led a team of 6 through acquisition.
Best fit: founders with a clear idea and the budget to move fast. You might have Figma mockups, a vibe-coded prototype, or just a well-defined concept. I bring product direction alongside the engineering.
I've been working as a software engineer for 6 years. I would describe myself as a generalist. I've worked in different domains such as aerospace, automotive, and telecom. I've taken projects from 0 -1. I'd like to move away from the enterprise environment and work in a smaller, energetic, and dynamic startup. I'm prepared to wear many hats.
Remote: optional, open to in-person in the NY area.
Willing to relocate: probably not.

Not necessarily looking for full time employment, if someone just wants to do a trial via part time / fixed duration project, that would be even better for a start. My last 3 full time roles started like that.
Remote: Open to remote or hybrid/in-office in SF Bay Area
Willing to relocate: Open to west coast
Technologies: Full stack web dev for 15+ years in many forms. In recent years I've been focused on game development projects using Babylon/WebGL and working with C++ & Go server-side (MMO servers). Many years of project and product management as well.
I have some cool projects! See my personal site for email and some of those projects:
Coolest released one is probably https://www.idlequest.net/, which is an idle-game web-based version of classic EverQuest, complete with its original 3D graphics in-browser and a real-time MMO server! Had up to 70 players online at the same time a month or two ago.
About to release my biggest project, which is a full reverse engineering and re-implementation of the 2007 MMORPG "Vanguard".
Looking largely for product engineering positions, or project/product management style work. Have done both and enjoy both a lot. Open to contracting or full-time.

I'm a generalist software engineer with most of my experience (14YOE professional) in backend, platform, infra, and DevOps stuff. I'm currently employed and love where I am and what I do, but I intend to relocate to the EU in 2028 and my job (federal contracting) is incompatible with that goal.
I'm very interested in deep learning, formal verification, and compliance automation, but also artificial life, complexity science, robotics, cybernetics (as in Beer), computational social sciences, network science, transit, city planning, etc.
I use Claude Code happily at work, as directed, and seen significant (though not unqualified) productivity gains. I've used it to varying degrees on different personal projects. I'm avoiding it now on personal projects (to retain and build skill). I can work anywhere along that spectrum.
I enjoy learning about what other people are working on, so even if you're not hiring or not interested in hiring _me_, I'd love to connect. I've had some genuinely transformative conversations with people I've met on HN, and I'd love to have more.

Open source maintainer/top contributor of AnkiDroid: Android client for Anki. 10M+ downloads.
~10 YOE, with 6 YOE open source (4,000+ commits). Ready for stability after years of contracting and maintainership.
I lead a global volunteer team and take full product ownership: setting direction over multi-year horizons, planning and implementing architectural migrations, and keeping a project moving via community engagement, triage, fixes, reviews and mentorship.
Highlights:
- AnkiDroid now releases in tandem with upstream, rather than lagging behind by years
- Migrated a 15-year-old codebase from Java 7 to Kotlin, maintaining git blame
- Migrated to a common Rust-based backend. Android contributors are fully isolated from this complexity
- Improved app rating from 4.5 to ~4.8 stars, dramatically reduced crash rate
- Mentored hundreds of contributors and co-launched AnkiDroid's Google Summer of Code programme
AnkiDroid continues as a hobby; my day job is fully separate.
Looking for: full-time or contract. IC or EM, I'm nontraditional so I'm open to a conversation about which fits. Drawn to work that makes people's lives better, in any stack.
Senior software engineer, 20+ years on production systems. Working on neural nets since 1996 (neuroevolution, genetic programming) — multiple AI cycles' worth of perspective on what survives the hype.
Currently building a regulatory forecasting system for Polish law: ingesting statutes back to 1944, building a graph of legislation and amendments, reasoning about where the regulatory surface is moving. The hard problems are PDF → structured graph at scale and reasoning under uncertainty, not the model wrapper.
I also write about where AI coding agents actually work and where they quietly fail.
Best fit when the work is engineering-shaped — application/data rather than infra/SRE/Kubernetes-heavy — and the schedule overlaps EU hours.
Comfortable as autonomous IC or small-team tech lead. Domains where messy real-world data meets non-trivial reasoning are where I'm sharpest — regulatory, legal, scientific, financial.
I'm a high-agency, high-energy, eclectic, serious, fun, creative techie who's done lots of things at BigCos and startups. My happy place is working hard with smart people on something big and complex that makes the world better.
After several years in the consulting/contracting game, I am looking for an ambitious team to join. Maybe yours!
A few of my spinning plates right now: Golang inference worker, two Expo apps in TS/RN, Python data pipeline, AWS IoT for HVAC-adjacent devices, shared FFI components in Rust, and a HealthTech web app in TS/React.

Grug-brain engineer (https://grugbrain.dev) and recovering purist. I'd rather push the needle in the wrong direction fast and correct course than design the perfect thing for six months. AI embracer - I treat it as an exoskeleton, not a replacement.
Not a big fan of: calculator apps on Kubernetes, six-round interview pipelines, unpaid take-homes longer than 2 hours.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
My primary experience is subscription ecommerce (starting in tech support and moving into fullstack engineering) and fincom. I'm always happy to learn new tech, but I've mostly done Python and JS/TS in the past few years.

20 years engineering total, last 5 dedicated to platform/cloud at a regulated bank, leading the replatform of a contractor-built AWS multi-account into FFIEC/GLBA-compliant standards-based architecture. Stood up federated HashiCorp orchestration (Vault Enterprise, Nomad, Consul), GitLab Enterprise from inception, LGTM/OpenTelemetry observability instrumenting Java/Spring Boot services, and developer tooling distributed via a private Homebrew tap.
Most interested in observability platforms, data infrastructure, and AI engineering broadly — anywhere AI is sharpening human judgment rather than displacing it. Currently building out infrastructure tooling in Go using agentic workflows (Claude Code).
Works across the stack — each layer has its own problems worth solving. Publishes on engineering decision frameworks and AI-augmented development workflows.
Pursuing CKA. Not interested in defense, crypto, or gambling.

About: Currently investigating robotics planning with diffusion models at Oxford’s Visual Geometry Group, under joint supervision from João F. Henriques, Björn Ommer, and Christian Schroeder de Witt.
Previously, I worked at AWS as an Applied Scientist Dual Student, where I (1) developed a novel inference optimization technique yielding 13.4% higher accuracy against baselines, and (2) improved SageMaker's Autopilot forecasting solution, resulting in a 3.5% error reduction and 16% decreased latency in production.
I will graduate with an M.Sc. from LMU in August and am seeking applied machine learning roles to transition my research into production-level systems.

Hi, I am Jojo Feng, a software engineer with 5 years of professional experience crafting mobile experiences. I started building mobile apps when I was in junior high, it was 2013, back when the Windows Phone was still a thing. I was appealed to the design system of Windows Phone (also because I was not able to afford a MacBook) so I learned C# and XAML after school and started build apps for it. Seeing positive reviews of my apps from users and how they provided values for them motivated me to pursue a career as a mobile engineer, and to this day, I'm still trying my best to bring the best mobile experience to those in need.
Full-stack JavaScript-focused engineer/entrepreneur with lots of experience in building scalable single page apps in different frameworks, web3, multiplayer web games, building transformers and other networks, all sorts of things. Product-oriented, executive and leadership experience, comfortable in both autonomous and collaborative settings, capable Linux sysadmin. I know how to ship, end to end.
I've focused for several years now on agentic and generative work such as simulating networked LLM-augmented embodied agents, interface research, too much to list here but always happy to talk more over email. While the rest of the industry is just starting to latch onto agentic systems, I can offer years of experience, product insight and leadership.
Available for consulting, startups, projects, anything web or agentic.
I've been using Go as my primary language for the last nine years, although I don't overly care about the specific language and have experience with a wide variety of tools and languages such as Python, Ruby, PHP, C, JavaScript, Lua, and probably some more. While I've mainly focused on backend in the last few years, I also have written plenty of frontend code over the years, from the "pre-jQuery" days to VueJS.
In the last few years I mainly focused on GoatCounter (https://www.goatcounter.com) with the occasional contract job, but I'm keen to start working on something new for the longer term.
I've got quite a bit of code on my GitHub, so you can take a look at that if you want: https://github.com/arp242

Email: (in my resume)
Compensation Expectation: $140k and $170k USD gross yearly
Hello Hacker News! I'm a CompSci PhD (AI Multi-Agent systems... doing Agents' research back in 2004, before they were cool haha) and a passionate technologist with a warm spot for building high-impact products and teams.
For over 20 years, I've loved being a hands-on leader in FinTech, building everything from scalable crypto trading desks and AI/ML systems for fraud detection, to migrating entire platforms from monoliths to robust, cloud-native microservices. I thrive on aligning engineering with business goals and tackling complex distributed systems challenges.
Zero-to-One Success: Built foundational tech/AI/ML at a Fintech, enabling the company's Series A. Executive & Scaling Experience: CTO of a crypto trading desk; Head of Engineering, Product or AI/ML at high-growth FinTechs.
I'm actively looking for a remote role, or for an absolute amazing opportunity, I would relocate. I am most comfortable as first/founding engineer, also have been head-of-tec/cto building startup's technology teams. Right now I am most interested in doing AI/LLM work, like really pushing the status quo of both the Engineering and AI/ML. (I would love to get into something like SSI).
A couple of interesting personal projects I'm working on now:
* I trained a couple of Transformers+MoE models to forecast the price of a REIT-like time series in Mexico (called FIBRA in Mexico): They observe heavy cyclical behaviours every quarter that can be isolated and used as information for forecasting. Good results, albeit not 'life changing' yet.
* I'm working on a "live weight adjustment" or "live training" framework for Transformers/MoE models to be able to use new information to modify the weights of the network slightly, without having to re-train the whole model. Kind of like LoRA/QLoRA, but making something usable for a live-running model.
* I am also experimenting with non-chat uses of text/token LLMs. LLMs are text generation machines, which leaving them "running" independently would be akin to our (people's) train of thought that starts since we are born. Having an LLM do that and finding ways give it "perceptors" for inputs (like IRQs in computers) for environment communication could yield interesting results.
I'm looking to do something interesting with good people. I'm thinking something pretty niche that's a real product and not some AI-based deal. Not that I have anything against AI, I kind of just don't want to chase the fad, you know.
The last thing place like that where I worked, iCare (formerly Centervue) makes fundus cameras for eye exams, and it was a really productive environment.
I don't need to chase a really high salary; I'm looking for something fun, challenging and meaningful.
HN isn't likely the place to look for it but I'm also kind of interested in something around housing policy or otherwise branching out from software. I've immensely enjoyed my volunteer work with a local YIMBY group (well, ok, I founded the group).
Software engineer with 8+ years of professional experience, focused on open-source developer tooling & build systems. 5 years at JetBrains. Ideally, I'd like my next job to be in Rust.
I do full-stack product design + development in one. In an agentic era, you don't need huge teams. If you have an idea, an LLM will vibe it most of the way, but won't think through real, human UX—I do. When you want to go all the way, hire me. https://inventbuild.studio
Technologies: A lot, but mostly focused around Rust, React/TypeScript, and macOS/Linux. I work mostly in frontend, desktop and compute, but have also done a bit of backend. I can pick up almost any tool or framework. I technically know Python.

I'm graduating in a month, so I'm seeking junior/graduate-level roles that revolve around backend and systems development where I can learn a lot. My experience includes four internships and multiple side projects (please check my resume and GitHub).
I started programming on my own at the age of 15. Since then, I have explored multiple areas, including mobile app development (native and Flutter), web development (React, Next.js, Vue), QA, MLOps, and AI/ML. During this exploration phase, I realized that I want to focus my career on backend development.
Most of my coding experience is in Java and Python. I also really enjoy Kotlin and am currently learning Go (Golang) by building a simple VPN as a side project. However, I am not limited only to these languages.

Hi, i'm Samir. I'm a junior software engineer with a B.Sc. in Mathematics & Computer Science (Data Science). I recently completed a contract at an AI startup where I built data-intensive React UIs. I also developed REST API endpoints, implemented full authentication flow with WorkOS, automated end-to-end type safety between FastAPI backend and react frontend and added CI/CD pipelines on GitHub Actions. I've also worked on some side projects like a Job Tracker SaaS and a Legal AI RAG assistant. Looking for my next full-time opportunity in backend, full-stack, or AI-adjacent roles.
Up to anything, be it backend, frontend, blockchain, compilers, DevOps, embedded or mobile. Bonus point if there is a little bit of Rust involved.
If you are curious my greatest project is WTX, a fast WebSocket framework and Database client that gave me a lot of insights about performance and code architecture. See https://github.com/c410-f3r/wtx.
For more information, take a look at my CV (https://c410-f3r.github.io/curriculum.pdf).
Currently employed but looking to build relationships with teams that value craftsmanship and velocity to grow my skills faster. I'm offering competitive rates ($60-90/hr) prioritizing team culture and interesting problems over maximizing income.
What I bring:
- Taste for type safety
- Pragmatic mindset (planning my solutions for regular delivery and avoid delay or drift)
- Dev tooling expertise (recently: custom Babel AST analyzers for faster debugging)
- Proactive problem-solver who likes to improve processes
Ideal projects:
- Teams with strong engineering culture who build ambitious things cleanly and fast
- Greenfield development or systematic refactoring
- Bonus: Highly formal/industrial model-driven environments and FP/Logic Programming environments (Clojure, Haskell, Prolog)

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.
I am open to work for a company anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up a team for you.

I started working with AI back in 2014 and consider myself one of the early vibe coders. I’m interested in everything related to AI and security, I’ve worked on benchmarks, optimizations, training and inference, tinygrad, H100, B200, DeepSeek etc. I also developed an ultra-fast programming language for executing complex GPU workloads and created a generative OS for it.
Under 25, I created the core of a security scanner and built a hacking team at a UK startup ($7M investment). We removed the GIL from Python to run 30,000 threads and scan 18,000 exchange IPs for malware overnight.
I have many achievements, I created a Top-10 music app on the App Store and an Instagram filter editor for a social network that had 28,000 users at launch.
I worked on a top-30 cryptocurrency in AI and built a better version of BitChat.

Hi, I'm Jonathan. I’m currently doing DevOps work for an open source project, operate a small web hosting company, and working as an accounting assistant for a local firm. My skillset is focused on the System Administration/DevOps side, with a bit of general dev experience primarily with Python. I have a PhD in Physics with my research focus being computational biophysics. On the side I also host my own infrastructure as a hobby, from the hardware to the nameservers and everything in between.
Having worked at startups before, I’m comfortable wearing many hats (and enjoy the variety).

I've mostly been a first or founding engineer, owning systems that have to scale early. I focus on high-throughput pipelines, messaging systems, media transcoding, and recommendations—areas where issues show up under load, retries, and edge cases.
I also build real-time dashboards to observe and control these systems, using local-first approaches and browser-based technologies for media processing and realtime communication.
- Messaging systems delivering millions of emails and push notifications in minutes (retries, deliverability, observability)
- Browser-based video editing and encoding platform using FFmpeg, Supabase, and AWS
- Real-time pipelines and recommendation systems for tens of millions of users
- Scaled event ingestion ~100x for analytics and experimentation
I do my best work in small, product-focused teams, owning systems end-to-end, staying close to production, and communicating early around risks and tradeoffs.
- Founding or early engineering roles (full-time, part-time, or contract)
- Backend or infrastructure-heavy work
- Products with real users or a clear path to them

Email: see resume
Hi! I'm Graham, a creative technologist, former YC W23 founder, engineer and designer. Especially interested in engineer roles where I can wear multiple hats and creative technologist roles. Need a technical person who knows how to build things zero to one, has strong backgrounds in both tech and art, and soft skills like marketing and communication? I'm your person!
I'm good at this sort of nitpicky work, spotting and thinking about edge cases. I like getting things exactly right, even though that obviously isn't always possible due to various constraints. I've been kind of wondering if I should get into embedded development; I find it appealing when things are low-level or similarly constrained. I've beaten Microcorruption. :) (The original levels, I haven't played the new ones.)
I'm also quite interested in unusual or obscure data formats, and working on Truffle Debugger and its associated libraries certainly involved a bunch of having to figure undocumented formats and interfaces. :) I put down above what languages I've worked substantially in but I'd say I'm a generalist and will figure out whatever you give me (I knew approximately no Javascript, Typescript, or Solidity when I started working at Consensys).
I'm a mathematician by background and in my spare time, so after the Truffle Debugger project was shut down I took some time off to focus on my mathematical projects, including old ones I've been shepherding through publication. But now I'm looking for work again! If you need someone like me, I'm available for hire!
Recently:
• Built and deployed a production RAG system (Python, FastAPI, React, Qdrant), including hybrid retrieval, ingestion, and backend APIs with improved retrieval quality and system stability as dataset scaled (ranking fixes, logging, debugging workflows)
Previously:
• 10+ years building and owning backend, data, and operational systems (ERP, BI, internal tools)
• Strong experience with messy data, integrations, and production debugging
• Delivered full systems end-to-end, including APIs, data pipelines, and internal tools
• Led technical delivery across cross-functional teams in complex corporate environments
Best fit: Backend or AI engineering roles where you need someone to quickly build, debug, or stabilize systems through API design & integrations, data pipelines, or LLM-powered features.
Open to contract engagements with possibility for longer term collaboration.
I spent a decade as CTO at EMEX, growing the engineering team from scratch through private equity acquisition. Today I operate through Brightform Technology, working with founders who need senior-level engineering without a full-time hire. The kind of problems where product sense and architectural judgment matter as much as code output.
Past work:
* Led all frontend architecture for an IoT platform processing high-volume sensor data across nationwide deployments. Built real-time building floorplan visualization, time-series HVAC dashboards, and a modular device configuration system.
* First engineering hire → CTO at EMEX. Built the flagship real-time reverse auction platform that drove seven-figure annual sales. Grew and led a team of 6 through acquisition.
Best fit: founders with a clear idea and the budget to move fast. You might have Figma mockups, a vibe-coded prototype, or just a well-defined concept. I bring product direction alongside the engineering.

Most recently founding engineer at Moar Market (leveraged farming on Aptos, ~$7.5M peak TVL) — owned the full stack: Move contracts, indexers, off-chain liquidation engine, DB design, and infra end-to-end.
Before that, tech lead at Hubble Exchange — built a custom EVM-forked L1 for orderbook perps that scaled to 50,000 TPS and 30M+ transactions, including the matching engine, indexing stack, and an SDK for market makers. Earlier: backend at Zomato (Hyperpure greenfield) and Delhivery (WMS, marketplace integrations with Amazon/Paytm).

I have some cool projects! See my personal site for email and some of those projects:
https://brynnbateman.com/
Coolest released one is probably https://www.idlequest.net/, which is an idle-game web-based version of classic EverQuest, complete with its original 3D graphics in-browser and a real-time MMO server! Had up to 70 players online at the same time a month or two ago.
About to release my biggest project, which is a full reverse engineering and re-implementation of the 2007 MMORPG "Vanguard".
Looking largely for product engineering positions, or project/product management style work. Have done both and enjoy both a lot. Open to contracting or full-time.
Email/LinkedIn/GitHub is on my website!
I'm very interested in deep learning, formal verification, and compliance automation, but also artificial life, complexity science, robotics, cybernetics (as in Beer), computational social sciences, network science, transit, city planning, etc.
I use Claude Code happily at work, as directed, and seen significant (though not unqualified) productivity gains. I've used it to varying degrees on different personal projects. I'm avoiding it now on personal projects (to retain and build skill). I can work anywhere along that spectrum.
I enjoy learning about what other people are working on, so even if you're not hiring or not interested in hiring _me_, I'd love to connect. I've had some genuinely transformative conversations with people I've met on HN, and I'd love to have more.

Email: dariusz@walat.eu
Senior software engineer, 20+ years on production systems. Working on neural nets since 1996 (neuroevolution, genetic programming) — multiple AI cycles' worth of perspective on what survives the hype. Currently building a regulatory forecasting system for Polish law: ingesting statutes back to 1944, building a graph of legislation and amendments, reasoning about where the regulatory surface is moving. The hard problems are PDF → structured graph at scale and reasoning under uncertainty, not the model wrapper.
I also write about where AI coding agents actually work and where they quietly fail.
Best fit when the work is engineering-shaped — application/data rather than infra/SRE/Kubernetes-heavy — and the schedule overlaps EU hours. Comfortable as autonomous IC or small-team tech lead. Domains where messy real-world data meets non-trivial reasoning are where I'm sharpest — regulatory, legal, scientific, financial.

About: I am a Generative AI Engineer who also happens to be pretty handy across the full stack. Most of my recent work has been building RAG pipelines, AI agents, and natural language search — using LangChain, LangGraph, and vector databases like Pinecone and ChromaDB — with OpenAI, Anthropic, and Gemini APIs under the hood. I care deeply about shipping GenAI features that hold up beyond the demo stage.
Beyond GenAI, I am working on the full stack — React/TypeScript on the frontend, Node.js or ASP.NET Core APIs on the backend, and AWS/Azure for infra. I like owning things end-to-end and building software that's simple and reliable.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Open to full time or contract.
I look forward to talking with you!

Independent systems developer, 27.
Filed US Provisional Patent #63/942,399 in December 2025 covering an offline memory lifecycle management system for mobile AI. Reference implementation on Android (M3mo Vault): FTS4 + TF-IDF hybrid search at 0.78 microseconds/memory on 10K-entry scale, 7-factor decay algorithm validated via ablation study (12x weight differentiation vs 2x baseline), 7-layer ServiceLocator DI replacing Hilt.
Also building Entropix Engine — a zero-GC browser game engine in vanilla JavaScript sustaining 3,000+ entities at 60 TPS. Structure-of-Arrays memory layout, GridHash spatial partitioning, deterministic fixed-timestep loop, featuring an adaptive grid-sampling fix resolving buffer overflow on high-refresh-rate displays. Live prototype on https://retroindex.org. 60 days into development, 13 milestones shipped. Weekly devlog on r/gamedev.
Past commercial work: scaled an e-commerce operation from $20K/mo to $140K/mo (7x) over 2 years through hand-coded HTML and SEO engineering — 700+ product pages under strict eBay platform constraints (no external CSS/JS allowed), with automated template pipeline reducing launch time 20%.
Background: BS Data Analysis Psychology, UC Davis (2021).

Hi, I am Jojo Feng, a software engineer with 5 years of professional experience crafting mobile experiences. I started building mobile apps when I was in junior high, it was 2013, back when the Windows Phone was still a thing. I was appealed to the design system of Windows Phone (also because I was not able to afford a MacBook) so I learned C# and XAML after school and started build apps for it. Seeing positive reviews of my apps from users and how they provided values for them motivated me to pursue a career as a mobile engineer, and to this day, I'm still trying my best to bring the best mobile experience to those in need.

Full-stack JavaScript-focused engineer/entrepreneur with lots of experience in building scalable single page apps in different frameworks, web3, multiplayer web games, building transformers and other networks, all sorts of things. Product-oriented, executive and leadership experience, comfortable in both autonomous and collaborative settings, capable Linux sysadmin. I know how to ship, end to end.
I've focused for several years now on agentic and generative work such as simulating networked LLM-augmented embodied agents, interface research, too much to list here but always happy to talk more over email. While the rest of the industry is just starting to latch onto agentic systems, I can offer years of experience, product insight and leadership.
Available for consulting, startups, projects, anything web or agentic.

I've been using Go as my primary language for the last nine years, although I don't overly care about the specific language and have experience with a wide variety of tools and languages such as Python, Ruby, PHP, C, JavaScript, Lua, and probably some more. While I've mainly focused on backend in the last few years, I also have written plenty of frontend code over the years, from the "pre-jQuery" days to VueJS.
In the last few years I mainly focused on GoatCounter (https://www.goatcounter.com) with the occasional contract job, but I'm keen to start working on something new for the longer term.
I've got quite a bit of code on my GitHub, so you can take a look at that if you want: https://github.com/arp242

Compensation Expectation: $140k and $170k USD gross yearly
Hello Hacker News! I'm a CompSci PhD (AI Multi-Agent systems... doing Agents' research back in 2004, before they were cool haha) and a passionate technologist with a warm spot for building high-impact products and teams.
For over 20 years, I've loved being a hands-on leader in FinTech, building everything from scalable crypto trading desks and AI/ML systems for fraud detection, to migrating entire platforms from monoliths to robust, cloud-native microservices. I thrive on aligning engineering with business goals and tackling complex distributed systems challenges.
Zero-to-One Success: Built foundational tech/AI/ML at a Fintech, enabling the company's Series A. Executive & Scaling Experience: CTO of a crypto trading desk; Head of Engineering, Product or AI/ML at high-growth FinTechs.
I'm actively looking for a remote role, or for an absolute amazing opportunity, I would relocate. I am most comfortable as first/founding engineer, also have been head-of-tec/cto building startup's technology teams. Right now I am most interested in doing AI/LLM work, like really pushing the status quo of both the Engineering and AI/ML. (I would love to get into something like SSI).
A couple of interesting personal projects I'm working on now:
* I trained a couple of Transformers+MoE models to forecast the price of a REIT-like time series in Mexico (called FIBRA in Mexico): They observe heavy cyclical behaviours every quarter that can be isolated and used as information for forecasting. Good results, albeit not 'life changing' yet.
* I'm working on a "live weight adjustment" or "live training" framework for Transformers/MoE models to be able to use new information to modify the weights of the network slightly, without having to re-train the whole model. Kind of like LoRA/QLoRA, but making something usable for a live-running model.
* I am also experimenting with non-chat uses of text/token LLMs. LLMs are text generation machines, which leaving them "running" independently would be akin to our (people's) train of thought that starts since we are born. Having an LLM do that and finding ways give it "perceptors" for inputs (like IRQs in computers) for environment communication could yield interesting results.

I'm looking to do something interesting with good people. I'm thinking something pretty niche that's a real product and not some AI-based deal. Not that I have anything against AI, I kind of just don't want to chase the fad, you know.
The last thing place like that where I worked, iCare (formerly Centervue) makes fundus cameras for eye exams, and it was a really productive environment.
I don't need to chase a really high salary; I'm looking for something fun, challenging and meaningful.
HN isn't likely the place to look for it but I'm also kind of interested in something around housing policy or otherwise branching out from software. I've immensely enjoyed my volunteer work with a local YIMBY group (well, ok, I founded the group).

I do full-stack product design + development in one. In an agentic era, you don't need huge teams. If you have an idea, an LLM will vibe it most of the way, but won't think through real, human UX—I do. When you want to go all the way, hire me. https://inventbuild.studio
