Systems engineer with 25 years of experience in government and defense cyber systems engineering, now building production agentic AI systems. I design multi-agent platforms with structured governance, hybrid LLM routing, and autonomous workflows for safety-critical environments. Every system I build prioritizes reliability, interpretability, and human oversight.
