What I'm looking for

I seek senior security roles where I can lead IR, automate workflows, apply AI responsibly, mentor teams, and improve enterprise SaaS security posture.

I am a Principal Security Engineer and Incident Responder with 15+ years of IT security experience, a Top Secret SCI clearance, and a track record of preventing major data leaks and improving security posture across large enterprise environments. I lead incident investigations for SaaS infrastructure, build automation (Python, Bash) to streamline IR workflows, design playbooks, and brief senior and executive leadership on incidents and post-incident lessons learned.

I have driven tool migrations (ThreatConnect to Tines), authored case-management frameworks, automated metrics and case handling, and contributed to AI/ML initiatives including OCI AI Foundations certification and prompt reviews. My recognition includes a CISO Coin, Verizon Spotlight and other awards for leadership, initiative, and operational excellence.
