I build software with AI agents, and I spend most of my time checking whether what they do holds up.

I'm co-founder of Play New and CTO of the Cosmico group. At Play New we turn companies into intelligences: we build a company's ontology from its own data, then put agents to work on it, first on the margin, then on the whole organisation. Outside the day job I run experiments and squeeze every bit of hardware I own: a software factory that works at night, evals built from my own merged pull requests. A few became tools I use every day. Most stayed experiments, and I keep them anyway: the repository is the notebook.

I learned all of it on my own, one job at a time. The long version is here.
