03 — About

A different path into code

Before software, I trained as a veterinarian and worked in poultry production. I moved into development through Microverse's remote full-stack program, pair programming with developers around the world, and went straight into building a production platform.

I'm used to working on my own and owning decisions end to end. I'm now looking for a frontend or full-stack role on a remote team. Spanish native, advanced English.

Let's work together.

Open to full-time remote roles and freelance projects.
