What I'm looking for

I seek roles where I can lead incident response and SOC maturity efforts, perform advanced pentesting and malware analysis, and grow within collaborative security teams focused on proactive threat detection.

I am a penetration tester and incident response professional with hands-on experience in offensive and defensive security, SOC operations, and malware analysis.

At ServiceIT I supported SOC analysts using XDR (Trend Micro), QRadar, and LogRhythm, helped build a CSIRT from the ground up, led war-room responses for major incidents, and developed use cases, playbooks, and SIEM rules.

I hold the DCPT certification and have completed extensive training in pentesting, blue team fundamentals, reverse engineering, and malware triage, with active participation on CTF platforms like TryHackMe and HackTheBox.

My technical practice spans manual internal/external pentests, phishing and social-engineering campaigns, binary exploitation, threat hunting, and tooling across SIEM, EDR, cloud, and application security stacks.
