Computer engineering graduate from the Faculty of Engineering in Rijeka, Croatia, currently working as a SOC Specialist at Span d.d. in Zagreb — watching the wire, triaging incidents, and thinking like the adversary on the other side of it.
My real passion sits on the offensive side: red teaming, penetration testing, and physical security assessments. I have a soft spot for OSINT and social engineering — the human layer is still the most exploitable protocol in production.
Linux daily driver for over a decade. Currently grinding through the Certified Penetration Testing Specialist path on HackTheBox Academy.
