About
Making educated guesses based on unreliable data provided by people who don't know what they want.
12 years helping teams improve reliability and change safety in complex distributed systems — most recently as Testing Lead at adidas, where I lead quality strategy for NEXT, the backend platform behind adidas's global e-commerce (€24.8B revenue, 2025).
My role is built around continuous awareness across four teams. I stay close enough to the code, the test suites, and the in-flight work in each team to drop in as an IC where the leverage is highest — the hardest production bugs, the risky changes, the framework decisions — while also setting the overall direction of each team individually and of the four as a group. The work sits at the intersection of testing strategy, automation engineering, and delivery improvement: defining testing scope, evolving API automation in Java and TypeScript, introducing contract testing and fast-feedback practices, and coaching teams to own quality rather than hand it off.
Recently leading the adoption of agentic testing approaches using Claude Code — helping teams ship faster with stronger confidence. I write here at That's a Bug. Ranked 9th all-time in QA & Testing on Stack Overflow.
My practice is rooted in Context-Driven Testing and Rapid Software Testing rather than ISTQB — testing as a thinking skill, not a checklist.
