Summary
👤
Senior🎓
Top SchoolVaclav Pech is a Senior Java Developer and technology evangelist based in Prague with over two decades of programming experience and 16 years in professional software roles, specializing in language engineering, domain-specific languages and concurrency. At JetBrains he blends hands-on backend development for the Meta Programming System with developer advocacy, and he founded and leads the GPars project to bring high-level concurrency abstractions to Groovy. An experienced lecturer at Charles University and conference speaker, he teaches modern programming language concepts and practical concurrency patterns. Curious about alternative paradigms, he explores languages like Clojure, Groovy and Haskell, and his open-source contributions include nuanced text-handling fixes in the widely used JetBrains MPS codebase—a signal of both deep codecraft and attention to developer experience.
