About

Who am I?

A cybersecurity engineer with a strong interest in defence issues, I work on systems and network security, as well as GRC. My conviction is simple: protection should not be a reaction, but an anticipation. I build security in from the design stage, so it strengthens infrastructures without complicating how they run.

As an auditor of the 164th IHEDN-Jeunes cycle, I strengthened my understanding of national defence and security issues, and a more strategic view of protecting national interests. As founder of Cybere and CoreCVE, I also build tools: a daily cyber threat newsletter and a public vulnerability catalogue. On assignment, I work on hardening, network equipment audits, compliance, and automation, with a pragmatic approach aligned with business needs.

At home, my homelab is always running. Firewall, switch, VLANs, and VPN for the network, DNS, reverse proxy, and a self-hosted PKI for trust services, Proxmox for virtualization, containers for services, GitHub runners for CI/CD, and a 3-2-1 backup strategy so nothing is lost. A personal space, driven by passion more than by work. It is my playground for freely exploring network architecture, containers, and DevSecOps.
