Rockstar🎓
Top SchoolDamien Duportal is a Staff Software Engineer with 13 years crafting CI/CD, Docker, and Kubernetes tooling, currently leading community-facing engineering for Jenkins at CloudBees. He blends hands-on DevOps and backend work—improving Jenkins pipeline libraries, Docker agent builds, and Kubernetes plugin lifecycle—with a strong emphasis on people, culture, and maintainable automation. A frequent contributor to high-profile open-source projects like Jenkins and Traefik, he has a track record of hardening build/test processes, adding shared library primitives (e.g., updatecli()), and fixing subtle concurrency and publishing issues. Beyond product work he teaches CI/CD and Docker, mentors engineers, and freelances, bringing both practical delivery experience and an educator’s clarity to complex infrastructure problems. Based in Liège, he pairs academic roots from INSA Lyon with a pragmatic focus on reliability and developer experience that often surfaces in behind-the-scenes pipeline improvements.
