Summary
🤩
Rockstar🎓
Top SchoolMartin Cimbálek is a pragmatic Java software engineer with 11 years of experience building backend systems and improving test quality, currently contributing at IBM after a multi-year tenure at Red Hat. He blends hands-on Java development with deep QA expertise—having driven test refactors, replaced deprecated APIs, and extended persistence and Drools compiler coverage in the notable Kogito cloud-native business automation project. Comfortable across databases, JPA persistence, and automated testing, he has a track record of making legacy tests more readable and reliable while adding OOPath and CRUD-focused test scenarios. Based in Prague, he is focused on returning to hands-on Java development roles where he can further grow his engineering craft rather than QA-only positions.
