Who I Am

Axel Gouriou

I'm Axel Gouriou, a French engineer specializing in electronics and embedded systems security.

I design embedded systems with an attacker's mindset and audit them with an engineer's understanding.

Based in Brittany, France. During the week, I work at my full-time engineering role. On the side, I'm available as a freelance for part-time missions, security audits, and consulting. Fully remote.

When I have free time, you'll find me hunting bugs on HackerOne.

Challenges are what drive me. The harder the target, the more interesting it gets.

Home Lab

Fully equipped for remote work. Soldering, debugging, reverse engineering, prototyping and 3D printing from home.
