At Spyrosoft, I’m building a Python and pytest system and network test framework, with 300+ automated test cases covering 250+ requirements. I use AI coding assistants to draft, refactor, and debug tests, then review and behaviorally verify each result before acceptance.

I independently built and operate Kubit.pl, a production operations and accounting web application with 64 backend and integration tests and 15 Playwright E2E scenarios gating every deployment. Previously, at ALTEN Polska, I coordinated and mentored a team of 15–20 on a data-validation project and helped shorten reporting time from 10 days to 5 within a 14-day sprint.
