About

I build things
that matter.

Studying Information Technology at Brno University of Technology. Focused on systems programming, network security and applied AI.

Currently working on a deepfake phishing simulation platform for my bachelor's thesis — helping companies measure and improve their security awareness.

When I'm not studying, I'm building side projects or thinking about ways to turn technical skills into real products.
