Python & Agentic AI Engineer · LLM Systems

Python engineer building LLM agent systems, with 15+ years shipping production software in banking and cybersecurity. I build agentic backends end to end: FastAPI services, LangGraph orchestration, tool calling, RAG retrieval, and the parts most teams postpone: evaluation, observability, token budgets, and a clear answer to where the data goes. Regulated clients taught me the gap between a working demo and a system a bank agrees to run.
