Threat Intelligence Investigations Security Engineering Malware Analysis Cryptography


I build security programs.

For more than two decades, I have worked at the intersection of cybersecurity, intelligence, investigations, engineering, and operational leadership. My focus is converting difficult security problems into capabilities that teams can actually operate: intelligence programs, investigative workflows, malware-analysis environments, deception systems, cryptographic security, and automation.

I am particularly interested in problems where the answer is not another dashboard or report, but a better operational system.

Areas of focus

Domain Focus
Threat Intelligence Nation-state threats, intelligence operations, threat hunting, collection and analysis
Investigations Cybercrime, intrusion investigations, complex investigative operations
Security Engineering Malware analysis, sandboxing, deception, automation, secure infrastructure
Cryptographic Security Key management, HSMs, cryptographic controls, post-quantum readiness
Leadership Building teams, programs, operating models, and durable security capabilities

Open-source work

I contribute to CAPEv2, an open-source malware analysis sandbox. Current work includes extending the platform toward Android guest analysis and improving the path from sample submission through install, launch, and process-lifetime observation.

Upstream contribution: Add first-phase Android guest analyzer — CAPEv2 #3210


How I approach the work

Evidence over assumption.
Operational capability over slideware.
Automation where it improves judgment, not where it replaces it.
Build for the analyst, investigator, and operator who has to use it at 2:00 AM.

Security is an operational discipline.
