About Me

A builder who likes the whole stack

I'm an AI Engineer at ArcFusion, contributing to the development of GenAI services. Before that, at Cynclair, I shipped a production LLM assistant for cybersecurity analysts - Neo4j, RAG, AWS Bedrock, end-to-end.

Master's in AI & IoT at SIIT, Thammasat - PM2.5 research published at IEEE iSAI-NLP 2023, an exchange at Tokyo Tech, and TA'ing Data Structures & OOP for 100+ undergrads along the way.

Off the keyboard, I enjoy cooking, writing, and helping my community.
