Rockstar🎓
Top SchoolRobin Ketelbuters is a Platform Engineer with 11 years of experience building cloud-native infrastructure, observability tooling, and developer-focused platform services from Utrecht. He is a notable open-source contributor and creator of Jaeger, co-founder of OpenTelemetry, and author of "Mastering Distributed Tracing," bringing deep practical knowledge of distributed tracing into production systems. Robin has shipped backend, DevOps, and UI improvements across high-impact projects like Jaeger and the OpenTelemetry Collector, often focusing on reliable startup/shutdown lifecycle, testing, and interoperability. His career spans hands-on roles at Giant Swarm, EDSN, Axual and Gluo, where he combined engineering and operational ownership to modernize observability and deployment pipelines. Comfortable across languages and layers, he moves between backend systems, front-end polish, and documentation to make complex systems understandable and resilient. A less obvious strength is his repeated work improving test infrastructure and CI, which underpins the long-term reliability of the projects he touches.
