Patryk Raba

Not a CV, and not a list of jobs. These are the four things I am proudest of - each one shipped, measured, and recognized by someone other than me.

01

Built the remote device lab that let Bragi test headphones from anywhere

As Head of QA/Release, product-owned the Remote Device Lab: physical smart headphones made remotely testable for integration testing with a mobile app - solving the hardest problem in wearable QA, where real Bluetooth hardware normally demands a device on your desk.

The lab served Bragi's whole QA operation - 10 internal members and 100+ external consultants across 12 parallel projects.

02

Cut QA execution time by 60% with agentic AI at MOSTLY AI

Introduced agentic QA in August 2025, before agent frameworks went mainstream: a 24/7 agent (LLM + Playwright + Jira) that turns natural-language requirements into executable test suites, plus AI-driven validation for synthetic-data generation - at a GenAI company, where the bar for “AI that actually works” is the product itself.

“He introduced AI agents for test automation, and under his leadership the QA team cut test execution time by 60%.” - Kerem Erdem, Chief Platform Officer & CISO, MOSTLY AI
