Ask HN: Freelancer? Seeking freelancer? (October 2025)

SEEKING WORK | UK | REMOTE

I'm a programmer with more than 10 years experience, primarily working remotely on a freelance or contract basis. My recent work has fallen into two main areas:

Scientific / numeric computing: e.g. I've contributed to research projects on quantum error correction and probabilistic programming languages. Tech: Python, NumPy, JAX, PyTorch, Matplotlib, JavaScript.

Backend web dev: e.g. I worked at a tiny start-up where I built a web app for automatic meeting scheduling. Tech: Python, Flask, SQLAlchemy, PostgreSQL, Celery, OAuth, Google Calendar APIs, AWS.

Please feel free to get in touch if you have a project (of any kind!) you think I might be able to help with, I'd be happy to chat.

SEEKING WORK | EU, Croatia (UTC+2) | REMOTE ONLY

Experienced full stack software engineer with a demonstrated history (10+ years) of working with enterprise solutions on premise and in cloud. I don't shy away from maintaining old code bases or learning new/old technologies and I'm very comfortable wearing many hats.

I love working directly with stake holders, even if they don't have engineering background. I can also team up with other freelancers and I know a few I've worked before in case you need more hands on deck, or need someone with a specialization, e.g. UI/UX design, translations...

Tech stack: NodeJS (Typescript), .NET (C#), VueJS, React, Blazor, PostgreSQL, MS SQL Server, DevOps, Docker
