About
I’m a Dutch engineer and ethical hacker based in Tilburg, NL — 20+ years deep in systems, infrastructure, and offensive security. When I’m not building secure-by-design platforms or red-teaming them to prove it, I’m probably deep in a Rust compiler battle, tweaking my Hyprland rice, or reading about adversarial machine learning.
My approach: understand the system better than anyone else, then break it before someone else does.
Daily drivers: macOS, Fedora Atomic (Cosmic), Arch Linux (Hyprland, Sway).
