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

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.

We're Stored – a digital payments startup redefining how merchants sell and get paid. We recently closed an oversubscribed funding round, driven by several new partnership agreements with some of the world's largest payments businesses.

You’ll be joining a small team where your work will have immediate and visible impact. The majority of the backend has been built by one of our founders, and you'll work closely with them to help take it to the next level.

What we’re looking for:

-Strong experience with C# and back end systems.

-Deep understanding of Postgres, performance tuning, batching, and scaling.

-Proficiency in TypeScript, and capable of owning full features end-to-end.

-Comfortable handling front end logic (we use Svelte, but experience with any modern framework like React or Vue is fine). To be clear, you won't need to design/build UIs, but you should be able to work across the stack.

-Experience with Linux and networking, especially profiling/debugging in high-traffic production environments is desirable but not essential

-Fluent in written and verbal English

-Self-disciplined, motivated, and able to manage concurrent tasks

This is a fully remote role, but we’re based out of London, UK and so only considering candidates in GMT/BST ±3 time zones who are willing to work between the hours of 8am - 6pm GMT/BST.

Interview process:

1) Initial video chat where we'll get to know you and ask some technical questions

2) Technical exam

3) Final call with the wider team

I am a Lead Infrastructure Engineer with 20+ years of experience.

Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.

I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.

I am located in EU (Estonia) and work remotely with occasional on-site visits.

The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.
