Please lead with either SEEKING WORK or SEEKING FREELANCER,
your location, and whether remote work is a possibility.
Please only post if you are personally looking to hire a freelancer or work as one. Agencies, recruiters, job boards, and so on, are off topic here.
My latest projects have been in full-stack edge ML R&D, memory controller firmware dev for POWER servers, and chip bringup/testing for Z mainframes.
I'm passionate about modular synthesis and tinkering with all sorts of analog circuits and DSP. Currently upskilling in analog PCB design and refining my abilities in FPGA development. Also WIP on a 3D-printed robot arm to practice control systems and actuation.
Technologies: Javascript, TypeScript, Node.js, Next.js, React, Python, Docker, Kubernetes, Terraform, AWS, GCP, SQL/Postgres, MongoDB, Redis.

I’m a generalist engineer with past experience including full-stack engineering at a YC legal-tech startup and full-stack + cloud infra at an NYC quant fund. I also have entrepreneurship experience that gives me an understanding of the end-to-end product development process at early stage startups.
My current project is a study mode for AI assistants with spaced repetition integration: https://app.polymax.ai/study-mode
I’m skilled at taking initiative on projects and synthesizing requirements from multiple stakeholders into meaningful technical solutions. I’m passionate about functional programming, building reliable and scalable distributed systems, and optimizing developer experience. I also speak 4 languages (English, Sinhala, Mandarin Chinese, and Thai).
Have a new product launching soon? Or some content you have been meaning to get to?
Hi, I'm Jeremy, an ex-software engineer who writes about tech. After helping build a cloud storage unicorn, I got into teaching developers and found out that I'm pretty good at making complicated stuff make sense. Now I write technical content mainly for SaaS companies. Happy to also chat about open-source, cloud architecture, or where tech content is heading.

My Main Services
- Blog Writing: I turn complex tech topics into articles people actually want to read. Whether it's deep dives for your engineering audience or guides that won't scare off beginners.
- Topic Planning: Not sure what to write about? I look deep into what your users care about and map out content that'll actually help them while helping you grow.
- SEO That Makes Sense: No keyword stuffing here - just strategic writing that helps you show up when people Google their problems.

In past 20 years did many different projects, mostly worked with teams 1-5. 60% of projects were related to sport and TV, rest was various other fields. I was jumping between leading, architecting, designing, programming and things in-between :)
Last years I programmed mostly in C# (web services, aspnet, razor, ...) also desktop apps (WinForms, WPF, Avalonia), JS/Typescript (mostly for gui, I enjoyed mithril and now SolidJS). I also did some c++ for various small integrations (for example some plugin for Godot, some ffmpeg, ...) and lately doing Rust – network programs. I mostly worked with GPC 70% , AWS 20%, other 10%.
I like to make GUI/backends that makes sense, are easy to understand (test with users) and performant/fast. Also to last years, with minimum dependencies.
I also have experience with live events setup for broadcast of events, have experience with networks.
I did tons of remote support with people around the world, also know how to use this information to make better programs (or design...).
Looking for 20-100 hours per month.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Built and sold a B2B SaaS company serving Fortune 500 brands with e-commerce intelligence and compliance. Now seeking to lead product/innovation teams solving complex problems at the intersection of data, AI, and scalable systems.
* Open to fractional, advisory, or full-time roles.
I like to make projects with personality. I'm pretty decent with UI, UX, architecting things and prototyping complex apps. I have a nice job experience in different startups, research centers and in FAANG-like companies. (I can send CV upon request)
As a example of things I like to do I put together a small collection of experiments with funky UIs that leverage LLMs behind the scenes. Give them a try and let me know what you think!

PHP/JS/TS Development, Extremely competitive rates available.
I build new projects and revitalize legacy code. I work mostly with Laravel and React/Inertia or Livewire.
I integrate modern tools pragmatically, adding real-time features via Websockets (Laravel Reverb etc) and AI capabilities like RAG for context-aware search and content generation.
I develop methodically – implementing tests for new features and maintaining clear documentation while keeping sharp focus on shipping tangible results. Through proactive communication, we'll collaboratively define the sweet spot between code quality and delivery pace.
I can help you build full-stack apps using any of the following technologies:
- Python - Django - FastAPI - Typescript - React - HTMX - AlpineJS - TailwindCSS
My latest project is ClaroHQ (https://clarohq.com) - a time blocking and invoicing app for freelancers. I built the project from scratch using Django, HTMX, and AlpineJS. I also handle deployment using Docker to a server on Hetzner.
Basically, I can help you go from Zero to One. I'm available during Euro timezone. Visit my website for my email address (link in my profile).
Well versed in python and javascript, but capable in other languages as well (the majority of this past year has been writing zig, and have deployed Java/Golang/C/Dart recently).
Commonly found using Django but not restricted to that. Lots of experience with modern react/vue as well as Flutter. I've been a remote worker for a decade now, so I had a track record of getting things done without direct supervision. I live in the UK but can and have worked with US entities.

I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.
