Projects I've worked on

Every project left me something: a new technique, a problem I hadn't solved before, or a different way of thinking about front-end. These are the ones I most enjoyed building.

Notes

Wins

25+ sites at Futbol Sites, some of them with over 5M daily users. Plus full-stack development for a ride-hailing app with 5k+ downloads.

Portfolio concept

I wanted a pixel-art look that felt like a game, without giving up a UI that is fast, accessible and actually works.

Side skills

WordPress, Shopify and technical SEO when they're needed. I lay out my own designs in Figma and I'm comfortable on full-stack work. Plus plenty of communication and good energy on the team.

Philosophy

Code someone else can read six months from now — me included. And the motto I've carried since I started: never stop learning.

AI

I use it as a copilot: it speeds up the repetitive parts, lets me argue ideas out loud and gives me feedback on my code, so I learn while I build.

Fun facts

I got into programming because of video games — it was my dream as a kid. As an adult, a video explaining the algorithm behind a Pokémon battle was what pushed me to take my first course.
