About
Built and shipped production LLM agents including an AI patient appointment assistant for Kyron Medical that automated specialist matching and end-to-end booking with email/SMS confirmations and a voice mode. Strong focus on production reliability (double-booking prevention with DB constraints and pre-write checks), deterministic multi-step orchestration with LangGraph, and rigorous monitoring/evaluation using LangSmith trace replay for prompt regression testing.

Key Strengths
- Shipped LLM agent to production for healthcare appointment scheduling (end-to-end booking with email/SMS confirmations)
- Reliability engineering for real-world failure modes (prevented double-booking via pre-write availability check + DB UNIQUE constraint)
- Designs multi-step agent workflows with robust orchestration and concurrency (LangGraph fan-out/fan-in, deterministic reducer ordering)
- Uses structured schemas to validate LLM outputs between steps (Pydantic validation to catch malformed plans early)
- Builds graceful degradation paths when external dependencies/keys are missing (closed-book fallback, non-crashing error callouts)
- Production monitoring and iteration loop using LangSmith tracing + offline evals via trace replay
