Nathan Rihet · Osaka, Japan

Full Stack Engineer and Photographer

I’m Nathan, a Full Stack Engineer and photographer based in Osaka.

Current work

At Rokken, I build applications around computer-vision pipelines, from video uploads and review interfaces to GPU job scheduling and background workflows. I work mainly with TypeScript, Next.js, Python, FastAPI and PostgreSQL.

Previous experience

Before Rokken, I developed generative-AI applications at Capgemini, first during an internship and then in a full-time role.

I also worked as a freelance developer from May 2024 to August 2025, initially alongside my role at Capgemini. During that period, I built and launched DocsRetriever, a B2B document-search SaaS, and continued its maintenance and support through August 2025. The service is now offline; its case study documents the system and the decisions behind it.

I also designed and taught seven practical workshops on conversational agents to Master’s students at Université Côte d’Azur. The course materials remain publicly available.

Independent projects and photography

Outside work, I’m developing Kororo, a browser-based 3D puzzle game with a playable preview on itch.io. My photography covers portraits, cities and live events across France, Canada and Japan. The engineering projects explain how I build systems; the photography archive documents my visual work.
