About Me

From Breaking Systems to Building Worlds

I like figuring out how things work, whether it’s breaking into a CTF challenge, creating one, or building game worlds in Unity or Unreal. As part of Team bi0s, I’ve won global CTFs, built challenges for DFIR Labs, and even created game platforms that hide CTF puzzles inside them. I love making things that feel alive, that make people smile, and I love the process of tinkering, breaking things apart, and putting them back together better than before.
