I'm half-maker and half-breaker. I build and hack for the challenge and the truth while dreaming about a free world.

I'm a security researcher, bug bounty hunter, entrepreneur, and professor at the MSc in Information Security @ University of Porto. I'm a coach for the ECSC Portuguese Team and former captain of the xSTF CTF team. I started doing bug bounties in 2018, and have found some cool bugs so far. Also, I was the H1-202 MVH.

Currently, I'm mostly focused on my startup, Ethiack.
