Rockstar🎓
Top SchoolJames Munnelly is a Staff Software Engineer with over a decade and a half of hands-on experience building cloud-native, container-first systems, currently shaping platform reliability and security at Apple. He specializes in Go, Kubernetes, Docker and distributed build/test tooling, with prior roles at Jetstack where he helped organisations migrate to Kubernetes and contributed to prominent open-source projects like cert-manager, kind and controller-tools. James combines backend engineering, DevOps and infra work—ranging from multi-arch kind builds to improving Kubernetes code generators—and has a history of productionising systems across AWS and Google Cloud. He’s comfortable across the stack, from webhook and certificate management implementations to frontend docs for cert-manager, and often bridges gaps between projects through dependency and CI maintenance. Based in Birmingham, UK, he values collaboration and continuous learning, and brings a practical open-source mindset that surfaces in both large community projects and his personal tooling.
