What I'm looking for

I seek a hands-on security engineering role focused on threat hunting, incident response, SIEM tuning, collaborative SOC work, and opportunities to reduce detection time and improve defenses.

I am a Senior Security Engineer and experienced threat hunter with seven years of hands-on experience building threat-hunting strategies, reducing threat dwell time, and improving detection accuracy. I leverage the MITRE ATT&CK framework, custom YARA rules, and automated Python/PowerShell scripts to accelerate investigations, enhance mean-time-to-detect, and drive measurable security outcomes.

I have led incident response and forensic investigations, tuned SIEM detections, analyzed logs across diverse devices, and communicated effectively with clients to meet security requirements. I hold certifications including CEH and CCSK, and I bring practical experience with tools like Nmap, Kali Linux, Burp Suite, Palo Alto, IBM QRadar, AlienVault, and various endpoint and network security solutions.
