AI engineer and systems architect with 30+ years of software engineering experience, specializing in defense, national security, and regulated industries.

My career spans a rare combination: from designing a real-time radar scheduling algorithm that achieved a successful missile intercept at White Sands Missile Range (for USMC, via Martin Marietta/Lockheed Martin) to deploying containerized ML models at scale for real estate AI companies. Currently leveraging AI-native development workflows and multi-agent orchestration to deliver solutions at 10-50x traditional velocity. Building production MCP servers and lightweight RAG architectures for persistent context management. I work across the full ML lifecycle: model training, CI/CD for data science teams, containerized inference pipelines, and cloud deployment on Azure and AWS. Stanford-trained in machine learning (Andrew Ng, pre-Coursera). Harvard-trained in business. Equally comfortable presenting AI strategy to executives as writing production Python — the strategist and the buil
