Flexible, self-driven engineering leader and test engineer. BA in Informatics, pursuing a Masters in Psychology at SWPS. Known as “PaaS — Patryk as a Service.”
15 years building and breaking software across AI, pharma, health tech, consumer electronics, gaming, and XR. From crowdtesting 300 products at Applause to shipping agentic AI at enterprise scale — I thrive on making complex systems approachable and efficient.
Conference speaker at Agile Testing Days, TestWarez, Conselenium, and Test:Fest. Outside work, I run Poland’s largest Minecraft community and ship side projects ranging from brain wave visualizers to spatial computing apps.
