Experience

Feb to May 2026

Junior QA Engineer

Porsche eBike Performance

Sole active QA on the mobile app, owning test planning, execution and reporting across iOS and Android. Wrote Appium automation for regression flows so repeatable checks stopped depending on someone walking through the app by hand, and tested gRPC and HTTP endpoints against the application contract rather than only through the interface. International team, English as the working language. The role ended when the site closed.

2021 to now

Full-stack developer, freelance

Self-employed

Client work end to end: scoping, build, testing, deployment and maintenance in production. Branch workflow with pull requests, and GitHub Actions so projects deploy on merge rather than by hand.

Dec 2025 to now

Co-founder and developer

Led the frontend architecture, wrote the Python service that converts 3D files, and ran code review and the release process for two other engineers.

I build web apps, front to back. Most of what I actually know came from making things that had to work for someone other than me, whether that was a paying client, a course deadline or a group of friends who wanted to settle an argument.

The work I enjoy most has something moving in it. Prices arriving over a socket, a camera counting reps, traffic rerouting itself around a closed road. Those problems have a right answer you can measure, and they break in interesting ways when you get them wrong.

Day to day that means TypeScript, Next.js, Node and Postgres, with Python when the problem looks more like an algorithm than an app. I am comfortable owning something end to end, from the database up to the part a client has to be able to use without me sitting next to them.

Four months as the only QA engineer on a mobile app changed how I write my own code. Testing, reproducing a defect properly and reading someone else’s work carefully are habits now rather than things I mean to get around to. What I want next is a team where someone more experienced reviews what I write.
