Enric Trillo
Fullstack Product Engineer — London, UK
Production software,
end to end.
Nine years building and shipping on TypeScript, Next.js and Python — with Azure and AI as part of the toolkit, not a separate department. I take features from product decision to production across the full stack — no handoffs between specialists along the way.

About
I'm Enric Trillo, a fullstack product engineer based in London, UK, working through Metasyde.
I build and ship production software end to end: product thinking through frontend, backend, cloud and AI. In practice that's TypeScript and Next.js on the front, Python and Node behind it, Azure underneath, and AI work layered through the middle — part of the toolkit rather than a separate specialism.
