Technical lead of a team of 4 at the French National Education Ministry — defining standards, industrializing deployments (GitLab CI, Ansible, Rancher) and hardening security (DevSecOps, SAST). Red Hat Certified Ansible Automation Specialist (EX294). When not running production for 100,000+ users, I maintain my own homelab on Proxmox — reverse proxy, SSO, observability stack, multi-VLAN segmentation. I also build CLI tools in Rust, play CTFs, shoot photos, and do live sound engineering.
