Summary
🤩
Rockstar🎓
Top SchoolKevin Ratnasekera is a Senior Software Engineer based in Berlin with 12 years of experience building robust backend systems and integration platforms. He combines hands‑on engineering at companies like WSO2 and Care.com with deep, long‑standing open source leadership as a member, committer and former VP/PMC chair across numerous Apache projects. His work spans ESB and API gateway internals, MQTT and HTTP endpoint reliability, and data persistence frameworks—often improving protocol handling, reconnection resilience and test coverage. An active Apache mentor and Google Summer of Code advisor, he has shepherded projects from incubator stage to broader community adoption. Less obvious: Kevin blends production engineering with governance expertise, making him as comfortable refactoring URI template handling as guiding project governance and mentoring contributors.
