About me
I'm a physics-educated software engineer who builds LLM-integrated systems — RAG pipelines, agentic assistants, and Claude/OpenAI API integrations — on top of 25 years architecting enterprise-scale software (Fortune 500 insurance, defense). Recently I built a persistent-memory AI assistant from scratch: multi-agent, with a temporal knowledge graph, retrieval-augmented context, and Claude API orchestration. I bring production engineering judgment — CI/CD, DevSecOps, containerized delivery — so AI features actually ship and hold up. I'll tell you what's possible and what isn't, up front.
