Summary
🤩
RockstarJames Laverack is a Lead Software Engineer with 13 years of experience building and operating cloud-native networking and security systems from Bristol, UK. He combines hands-on backend and DevOps expertise with leadership in production-grade projects, notably contributing to the widely used Cilium eBPF project by improving etcd initialization, XDS TLS handling, and build/deployment workflows. Formerly a Kubernetes Release Team lead, he brings deep open-source stewardship and release management experience to customer-facing technical roles. At Cisco/Isovalent he blends architecture, reliability, and customer success to help teams adopt observability and secure networking patterns at scale. An engineer who moves fluidly between core protocol work and practical operational improvements, he’s as comfortable refactoring low-level subsystems as he is shaping release and deployment practices.
