About
Senior platform and test engineer with 15+ years of experience. I started my career at a VR startup as a programmer, and later moved more towards developer infrastructure and tooling. After that I had two roles where I got closer to testing as well (testing a flight simulator, and working on automotive navigation software).
In my current role I maintain and develop scripts in Python, administer Linux servers, manage CI/CD pipelines. I am currently based in Europe, but our family relocation to Christchurch is already in progress.
