Summary
👤
Senior🎓
Top SchoolPetr Plavjaník is a Master Software Architect based in Prague with 11+ years designing and building enterprise-grade, multi-platform applications—specializing in mainframes, DB2, and rich web clients. He blends deep systems-level experience (HLASM, z/OS, C/C++) with modern stacks (Java, Python, JavaScript, Spring, React) to modernize legacy products and expose mainframe data via RESTful APIs. At Broadcom/CA he led UI and application-layer teams, introduced test-driven and automated end-to-end testing frameworks, and helped ship Mainframe 2.0 initiatives and DB2 performance tooling. He’s equally comfortable optimizing database performance and architecting high-availability services, often bridging gaps between DBAs and developers. An enthusiastic lifelong learner, he’s been extending his toolkit into Hadoop, Scala, iOS and bringing modern automation and Node.js/Java tooling to z/OS. Colleagues rely on him for pragmatic architecture, mentorship, and turning legacy constraints into maintainable, testable solutions.
