What I'm looking for

I seek senior roles leading GRC and security automation where I can modernize compliance, reduce remediation cycles, and align security with engineering and mission goals.

I am a U.S. Air Force veteran and GIAC-certified information security professional with 13+ years of experience across DoD, the Intelligence Community, and enterprise environments. I specialize in managing end-to-end GRC programs, policy lifecycle management, third-party risk, and POA&M lifecycle tracking.

I bring deep hands-on experience with NIST RMF / 800-53 control testing, SOC 2 audit evidence coordination, and vulnerability translation from Splunk, Tenable, and Nessus into prioritized remediation roadmaps. I build GRC automation workflows using Python and PowerShell to streamline evidence collection, control testing, and compliance reporting.

I communicate risk to technical and executive stakeholders, apply MITRE ATT&CK and OWASP LLM Top 10 for adversary-informed control decisions, and modernize compliance operations through AI/ML governance and tooling. I hold an active DoD security clearance and multiple certifications including GCIH, GSEC, CompTIA CySA+, Security+, and PenTest+.
