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
>_

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 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.
