Message

At Möbel Pfister AG, I defined test strategy and release quality gates across two interconnected systems, working with Product and Engineering on regular production releases. I also managed and developed a five-person QA team.

I applied shift-left testing to identify requirement gaps and quality risks before development. I developed and maintained Playwright tests in JavaScript for high-risk end-to-end scenarios and critical user flows.

Earlier, at MobiDev and NearShorePartner.ch, I tested web and mobile products, REST services, and cross-system data synchronization. I hold the ISTQB Certified Tester Foundation Level certification and have used ChatGPT and Claude to improve QA workflows.
