Raihan Satria — AI Product Engineer & Design Technologist

Based in Tokyo. Currently working at Honda Motor Co. on agentic AI systems and human-centered design. Master's in Media Design from Keio University (Dean's List). Background in Mechanical Engineering from Universitas Indonesia.

I believe technology should feel human. My work focuses on the intersection of agentic AI systems and human-centered design — turning complex information, like road safety regulations or organizational knowledge, into intuitive, high-accuracy conversational experiences.
