Profile
Networking and cyber security student with a red-team mindset. My roots are in computer networks, and my focus now leans offensive — web application pentesting, network enumeration, and Active Directory basics — practiced in the lab and documented as clear, reproducible writeups. Active in the security community through COCONUT Computer Club and regular CTF practice.
Informatics Student — Cyber Security Concentration. Every finding is documented into a reproducible writeup — from exploitation steps to mitigation recommendations you can apply right away.
