Summary
🤩
Rockstar🎓
Top SchoolArthur Outhenin-chalandre is a Staff Site Reliability Engineer based in Paris with 11 years of experience building and operating cloud-native infrastructure for security- and privacy-focused organizations. He combines deep systems and networking expertise—demonstrated by notable contributions to Cilium (eBPF networking) and Kubespray (production Kubernetes deployments)—with hands-on storage SRE work on Ceph at CERN. Arthur has advanced CI/CD, dependency upgrades, and complex network plugin integrations, and he’s comfortable moving between Go, Ansible, and lower-level UNIX/C work. Known as an open-source contributor, he often tackles subtle edge cases (egress gateways, kube-proxy replacements) that improve reliability at scale. His background spans both academia and industry, giving him a pragmatic engineering approach grounded in strong teaching and mentorship experience.
