👤 About Me

For over six years, I've dedicated myself to learning the ins and outs of IT, sharpening my focus on offensive security. I thrive in the high-pressure environment of Capture The Flag (CTF) competitions. Beyond the keyboard, I balance my technical pursuits with my studies at an Economics high school and the discipline of MMA (Mixed Martial Arts).

🇪🇺 Elite Training: ECSC

Letní škola Kybersoutěže

The "Letní škola" is an intensive, invitation-only cybersecurity summer camp — the official preparation and selection event for the Czech national team at the European Cyber Security Challenge (ECSC).

Handpicked as one of the top talents from the national competition, I trained with finalists and industry experts to represent the Czech Republic on the European stage. The curriculum involved deep dives into advanced CTFs, complex offensive/defensive labs, and elite teamwork exercises.
