01 · About

Builder of production systems.

Full-Stack AI Systems Engineer focused on RAG pipelines, LLM agents, and cloud-native architecture — designing systems that move beyond demos into production. I've shipped TradeAgent AI (a LangGraph + Twilio + Deepgram voice agent for tradespeople), AgentAudit OS (LLM compliance observability with hash-chain audit logs spanning EU AI Act, NIST AI RMF, ISO 42001, SR 11-7 and HIPAA), and MedScribe AI (HIPAA-aware clinical SOAP notes on Deepgram + Gemini), alongside production SaaS work at Upstrapp Inc. I favour explicit state machines over open-ended LLM loops, ship production AI + SaaS for global clients, and measure work in outcomes — latency, reliability, audit trails — rather than prompt cleverness.
