Nguyen Quang Thao

About

I'm Nguyen Quang Thao, an AI engineer and backend developer focused on agentic AI systems — multi-agent orchestration with LangGraph, retrieval-augmented generation, and LLMOps — backed by production-grade microservices in FastAPI, Node.js, and Spring Boot. I like building systems that go from notebook prototype to something that survives real traffic.
