What teams say after

Patryk is a strong engineer at heart. He introduced AI agents for test automation, and under his leadership the QA team cut test execution time by 60%. He would be a strong contribution to any team he joins.

Kerem Erdem - Chief Platform Officer & CISO, MOSTLY AI[pdf] Recommendation letter
>_

Patryk is someone who will get things done - big or small doesn't matter. Smart, knowledgeable, accountable, and everyone wants him on their team.

Abhilasha Rathi - QA Manager, Welltok
>_

Patryk is professional and caring, and works effectively in difficult situations where multiple conflicting demands make a good solution hard to find.

Patryk always showed great proactivity, anticipating issues and proposing ideas to overcome them. He implemented several processes that the whole company adopted as part of its QA and release process.

Jose Gorchs - Software Product Owner
>_

Patryk juggles multiple projects without ever lowering standards. His attention to detail is some of the best I've seen - when he says something is tested, no use case was missed.
