About
Since 2021, I have worked on network and security for EDF's critical infrastructure. I started as team lead on the migration of 200+ firewalls, then took part in rolling out a new Aruba / Fortinet architecture, and finished in L3 support until June 2026: troubleshooting, CVE follow-up, IPS sensors, acceptance testing and qualification.
I mostly work on firewalls (Fortinet, Juniper, pfSense), Aruba Wi-Fi with ClearPass and monitoring (Zabbix, Grafana, SolarWinds Orion, Centreon). On the systems side, Proxmox and vSphere, plus Python / Bash for automation.
I've been building a homelab since 2012, and it has grown into a real small infrastructure: pfSense and UniFi with separate VLANs, WireGuard VPN, internal PKI, a 4-node Proxmox cluster, an Unraid NAS, Frigate for the cameras and Home Assistant for home automation. It's where I try things I can't try at work. I also use AI (Claude, Claude Code on the command line) as an assistant to save time on some tasks: reviewing a script, checking a config, structuring docs or drafting a commit message.
I hold a Master's-level engineering degree in Networks & Cybersecurity from CESI (2017-2021), after a BTS SNIR and a STI2D baccalauréat at Lycée Henri Loritz in Nancy. I'm now looking for a job or contract on this kind of infrastructure (firewalling, network architecture, access security), with the aim of gradually moving towards operational security.
