I build AI systems and run them in production.
Right now I'm building Merlin Cloud, an agentic coding platform I designed and operate solo. Open source, in production. It started because I wanted a proper dev environment on my phone in the AI era.
With a friend, I'm also making Out of Body, a puzzle game written in Jai with a custom engine, launching in 2026 on Steam. I do the programming, game design, level design, and music.
I've been coding since 2001, when I was 13, and professionally for fifteen years, in startups as well as big companies. The last four of those I spent designing and running the financial data platform at XBTO, a crypto-finance company.
Outside of code, I'm a dad first.
I write here about AI, building Merlin, and game development.
Stay curious,
Arnaud
