I’m Raphaël, a software engineer based in Lille, France, working at the intersection of low-level systems, networking, and security.
Background#
I currently work as a development engineer at Stormshield, where I build security-oriented software in C and C++. Before that, I spent time at Capgemini as a software engineer, and at Thales (Belgium) as a software test engineer on embedded Linux systems.
On the side, I’ve taught algorithmics and C programming at JUNIA ISEN Lille, the same school I graduated from. I also run a homelab and enjoy tinkering with infrastructure: Kubernetes, GitOps, VPNs, the whole stack.
