AI Engineer • LLM Specialist

Building Intelligent Systems & Production-Grade AI

AI Engineer at ArcFusion, specializing in end-to-end LLM pipelines, RAG systems, and cloud-native AI solutions. Passionate about turning research into real-world impact.

From Research to Production AI

I'm an AI Engineer at ArcFusion with a Master's degree in AI & IoT from SIIT, Thammasat University. I build end-to-end AI pipelines — from data engineering and model development to production deployment on cloud platforms.

My journey spans academic research (published at IEEE iSAI-NLP), production LLM systems with knowledge graphs, and teaching 200+ students. I'm driven by the challenge of making AI systems that are robust, scalable, and genuinely useful.

“Dedicated to developing end-to-end production AI systems while continuously learning and sharing knowledge with the next generation of engineers.”
