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.

I have 14 years of experience in Fin-Tech, Journalism, TV and Media, Health, Science, and love working with startups!
I've taken countless projects from 0 to 1 working with clients like JPMorgan Chase, Santander Bank, Rob Walling, Trello, Peter Diamandis, Syncthing, SimplyCredit and others. I'm experienced in Vue.js, Django, Phoenix framework, Quasar, just to name a few. I pick up new tech easily and like working on complex products.
I can help you with:
- Product Design: I help identify and solve the real problems your users face. Whether you're struggling with low engagement, confusing user flows, or a product that doesn't quite meet market needs, I dig deep into user pain points to design solutions that actually work. From ground-up product strategy to fixing specific friction points that are hurting your metrics.
- Front-end Development: I can turn the design into a pixel perfect product. Being able to design and develop allows me to move at speeds otherwise impossible by cutting a lot of the steps otherwise needed.

My name is Burhanuddin Rashid, and I am a software engineer with 8+ years of experience in developing mobile applications. I am an open-source enthusiast and a Google Developer Expert in Dart and Flutter.
I owe most of my career to the open-source community. I got exposed to this when I open-sourced my first Android PhotoEditor library, which reached around 3.8K stars and is still active. This led me to an opportunity to speak at Droidcon Berlin 2021, sharing my open-source learnings.
My biggest contribution so far in the product was to improve code and app quality by introducing testing to the team. Before that, I was the Android tech lead to build an offline-first app to manage package delivery with real-time location tracking, collaborating with a remote team. Apart from this, I've also worked on web and backend technologies like React and Spring Boot, which gives me additional knowledge of how the system works end-to-end.
Also, in my free time, I learn and share my knowledge by writing blogs, newsletters, Youtube videos, or speaking at conferences.
Remote: Yes (20 years experience, efficient, productive, and highly available)
Willing to relocate: For the right position; remote with occasional travel much preferred

- CI/CD pipelines for ML deployments
- Making AI systems cost-effective at scale

I'm a fractional CTO and hands-on product engineer with over 17 years of startup experience. I help non-technical founders turn ideas into reality - working products and teams that provide a solid foundation for profitability, fundraising, and growth.
I offer the following services:
1. Product design - design a product that users want, investors back, and engineers can actually build.
2. Product development - build a quality product quickly and start gathering feedback from customers and potential investors as early as possible.
3. Engineering management - hire, onboard, and lead a lean engineering team to accelerate product development and optimize cost.
4. Technical consulting - pick a tech stack and processes appropriate for the current stage without putting future growth at risk.
5. Project rescues - get your project back on track, understand why it went off the rails, and ensure it'll stay on the right track.
If that sounds like what you need then let's chat: contact@gregnavis.com
I've worked across many stacks, but prefer tried and true tech: React + TypeScript or Hotwire on the frontend; Ruby on Rails on the backend. I also have significant experience with Elixir (+ Phoenix) and Python (+ Flask).

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 companies 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 your team.

Hi there! I'm Dylan Fitzgerald, a software engineering consultant with a knack for bridging the gap between technology and team dynamics. With a technical background in Ruby on Rails, Elixir, and DevOps, I excel in elevating the quality of projects while fostering a harmonious team environment. My years of consulting across the industry give me perspective on what works—and doesn't—with teams and process. In particular, I thrive on turning the implicit into deliberate decisions.
- Full-stack development with a focus on Ruby on Rails and Elixir ecosystems.

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).
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.
