What I'm looking for

I’m looking for a role where I can design, evaluate, and harden agentic LLM systems—RAG, tool-calling, and guardrails—with real production constraints, strong experimentation, and clear reliability metrics.

I’m an AI Agent Engineer and Computer Science graduate focused on turning LLM ideas into dependable products. I build agentic systems with Retrieval-Augmented Generation (RAG), tool calling workflows, and rigorous AI agent evaluation using LLM-as-a-judge approaches—always with guardrails, observability, and quality metrics in mind.

In my current work, I design evaluation workflows for tool-calling and skill-based agents, analyze execution traces, and improve response latency through prompt, routing, and tool-call optimizations. I also develop production-oriented AI apps like a FastAPI/NextJS communication platform with a RAG-first pipeline and evaluation monitoring (LangFuse, RAGAS), and a Vietnamese–English policy Q&A RAG chatbot with source-grounded answers, routing for cost/latency, and domain-specific safety guardrails.
