Senior full-stack engineer

Gabriel Carreras Albiol

Fifteen years shipping AI-powered products end to end.

I build and ship AI-powered products end to end: the data model, the API, the interface, the deploy, and the part where it has to keep working.

Local government in Menorca, agencies in the Midlands, and now my own company. Most of what I do is Next.js written from an empty folder, or WordPress and WooCommerce pushed further than they were designed to go.

Spanish, English and French. I care about software that keeps running after the demo, which is a different skill from making one.
