Summary
👤
Senior🎓
Top SchoolPiotr Kubowicz is a seasoned software engineer with 16 years of experience specializing in JVM-based server-side development, particularly Kotlin and Java. He helps teams maintain sustainable delivery velocity as code complexity grows by promoting effective processes, solid build setups, and pragmatic coding practices. At Nexocode and currently Superside he works on backend systems that intersect Big Data and Machine Learning, bringing hands-on experience from production and open-source work. His contributions to notable projects like pact-jvm (improving pact loading and verification) and Awaitility (refining Groovy integration) show a practical focus on testability and tooling for asynchronous and contract-driven systems. An active speaker, workshop organizer and blogger, he pairs autonomous-team coaching with deep implementation skills rooted in an MSc in Computer Science from Jagiellonian University. A less obvious strength is his attention to developer ergonomics—small infrastructure and test improvements he champions often yield outsized productivity gains.
