> Whoami
I started my journey into IT at 15, tinkering with microcomputer systems and networks. Curiosity led me to Web Development, but I quickly realized that my true endgame was Cybersecurity.
Now at 20, I focus on the Red Team side of operations. I love the thrill of solving complex puzzles and understanding how systems break, though I also deeply enjoy the defensive strategy of Blue Teaming.
Offline, I keep it simple. You’ll find me grinding video games, going to the gym, or spending quality time with my partner and friends. I’m just a guy who loves to learn, explore, and occasionally break things—ethically, of course.
