What I'm looking for

I’m looking to lead hands-on technical delivery of secure, compliant agentic AI and LLM systems—especially in regulated environments—while partnering with government/enterprise stakeholders to turn mission needs into scoped product requirements.

I’ve been the CTO at Agentic Secure, leading the design, development, and secure deployment of AI solutions for federal government and enterprise partners. I define technical strategy for secure, agentic AI in enclave-based AWS environments, direct end-to-end LLM-powered application development, and coordinate with AWS and external partners to validate architecture and compliance.

Before that, I worked on AI/ML and cyber tooling at Leidos (remote), including SOC/DFIR agentic systems that ingest CTI and SIEM logs, correlate events, generate rules, and map results to MITRE ATT&CK. Earlier roles included offensive security engineering, senior adversary emulation, and security architecture work at Sandia National Laboratory, where I led red team engagements and advanced embedded/ICS/IoT vulnerability research.
