What I'm looking for

I seek roles focused on proactive, intelligence-led defense and DFIR where I can lead threat hunting, build detections, collaborate with SOC/IR, and advise leadership on risk.

I am a cybersecurity specialist with hands-on experience in threat intelligence, threat hunting, and digital forensics, delivering intelligence-driven defensive strategies and rapid incident response across enterprise environments. I have led CTI operations, executive protection intelligence programs, and advanced threat-hunting campaigns using MITRE ATT&CK to identify IOCs/IOAs tied to APT groups.

I have executed DFIR for high‑severity incidents, run vulnerability assessments and BAS, and monitored dark, surface, and deep web sources to detect data leaks and threat actor activity. I collaborate with SOC, IR, legal, and physical security teams and produce strategic advisories and technical reports for senior leadership and clients to support risk‑based decisions.
