About me

I'm a student independently developing software in Java and Python. My main interest lies in cybersecurity: I actively practice on TryHackMe and Hack The Box and study networking, security principles and secure coding.

Beyond development, I build practical experience by analyzing and solving problems myself — from technical bugs in software to security challenges.
