About me



IT Security Engineer




I'm an off-road programmer but Python tends to be my favorite weapon when hammering is required.

I speak fluently Infrastructure As A Code, Continuous Delivery and, with even more enthusiasm, Continous Security Audit.

Scaling stuff, tracking down hot code paths and hunting vulnerabilities always get me excited.

I've been known to be an unflagging Digital Nomad moving around the world, a craft beer enthusiast and an unimpressive guitare player.
