Rockstar🎓
Top SchoolLouis Delossantos is a Staff Software Engineer with a decade of experience specializing in Linux systems, kernel networking, and distributed systems, currently focusing on Cilium and eBPF at Isovalent/Cisco. He designed and core-maintains ClairCore and Clair v4, open-source container security projects used widely in cloud-native ecosystems, and has made notable contributions to the popular Cilium project—improving BGP control-plane functionality and Kubernetes-native peering CRDs. Comfortable across systems, networking, and backend infrastructure, Louis blends low-level programming (kernel/eBPF, networking) with production engineering practices like observability and real-time streaming. He also builds productivity tooling in his spare time (Neovim plugins) and brings a rare combination of deep systems expertise and pragmatic product-focused delivery.
