Ṃanuel Moñino is a Release Lead with 16 years of software engineering experience and a deep commitment to open source, currently coordinating releases at Vaadin from his base near Madrid. He combines full-stack Java and frontend expertise—contributing to cornerstone projects like the Vaadin framework and vaadin-grid—with performance-focused backend work on Jenkins’ performance plugin. His career blends hands-on engineering and leadership, from technical director and VP of engineering roles to present release stewardship, and he also serves on the Apache JAMES Project Management Committee. He has a pragmatic track record fixing tricky client-server integration issues (caching, fingerprinting, touch-device interactions) and improving test suites and build pipelines. An MBA in Innovation complements his technical background in telecommunications and chemistry, giving him a rare mix of product-minded strategy and low-level systems fluency. He’s the sort of engineer who still dives into bug fixes in widely used open-source components while running release processes for production-grade Java web tooling.
