What I'm looking for

I want a hands-on security role where I can perform SOC duties, incident response, and red-team activities, learn from experts, and grow into senior security positions.

I am a driven cybersecurity professional with hands-on experience in SOC workflows, alert triage, incident investigation, response, threat hunting, and penetration testing. I achieved #1 in Romania on LetsDefend and HackTheBox, completed SOC Analyst and Incident Responder career paths, and investigated hundreds of alerts and targets with high success rates.

I hold 30+ certifications across incident response, SOC operations, offensive security, networking, and programming, and I recently completed a B.S. in Information Technology (2025). I learn fast, thrive in focused technical work, and am eager to kick-start my career while growing with a security-focused team.
