Banking sector · Enterprise systems · Now full-stack

Spent a few years building production apps for banks and enterprise clients — the kind real people depend on. Now going full-stack, and this portfolio is the first thing I'm shipping to prove it.

Live

Not a template. Built from scratch because I wanted something that shows how I think about code — the architecture, the design decisions, the things that don't show up in a GitHub readme.

About

I build interfaces — have been doing it professionally since 2022, mostly in the banking and enterprise world. The kind of apps that run on production servers and have actual users depending on them.

Lately I've been building the backend side too — not through courses, but by shipping real things and figuring out what breaks. This portfolio runs on a Postgres database, Prisma and its own auth-protected admin panel. I built all of it.

Open to roles where I can keep growing on both sides of the stack. Remote or on-site. Based in Elche, Spain.
