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.

Selected Projects

Safety Driving Education System — Honda Motor Co. (2025–2026)

An end-to-end AI platform that personalises driver education through psychometric profiling. 19 screens from DSQ assessment to AI-led lessons to e-certification. Predicted ~15% improvement in safety awareness from a Phase 1 simulation; deployed to production. Role: UX/UI Designer & AI Engineer. Tools: Figma, FastAPI, LangChain, Next.js, Azure OpenAI.
