I lead enterprise SOC investigations and incident response across global DoD networks.

Message

At Resource Management Concepts supporting MARFORCYBER, I lead SOC investigations, mentor analysts, and improve response operations across 200K+ endpoints and 300K+ users globally. I reduced the active incident backlog by 70% and built an incident detection certification program with a 90% first-time pass rate.

I've led classified data compromise and exfiltration investigations, threat hunting, and enterprise response to root-level intrusions, malware, insider threats, and unauthorized activity. Using Microsoft Sentinel, Microsoft Defender, MITRE ATT&CK, and DLP policy improvements, I reduced false-positive alerts by 80% and helped block 230K+ malicious emails monthly.

As a USMC veteran and former IT Director/co-founder, I also bring hands-on experience building IT and cybersecurity infrastructure, operating business systems, and growing sales through strategic marketing.
