Four apps. Eight years. A lot of Swift.
The projects I keep returning to. Each one taught me something I couldn't learn anywhere else.
Metrociego Madrid
Helping blind commuters navigate the Madrid Metro with confidence.
The app I started in 2017 and never stopped shipping. I rewrote it from UIKit to SwiftUI (80% less code, twice as fast), added Dijkstra-based routing on top of live GTFS data, and tuned every gesture for VoiceOver. What started as two friends' hobby is now in thousands of pockets.

Leisurist
A quieter way to track what you watch, read, and play.
My first solo indie bet. Built around SwiftData (I jumped in early) and RevenueCat for monetization, Leisurist pulls from TMDB and Google Books to keep a personal shelf of everything you've enjoyed. No social graph. No feed. Just you and the things you love.

Quizquake
A pocket-sized quiz game to challenge your friends.
A weekend-style project that kept growing. Quizquake is a multiplayer quiz you play against friends, with custom categories, error review and live stats. Firebase on the backend keeps rooms in sync. A reminder that sometimes the best apps start as jokes.

Greenie
AI plant identifier and care companion for iPhone.
My latest indie bet. Snap a photo and Greenie identifies the species, spots health issues and builds a personalized watering schedule. Built on the OpenAI Vision API with Firebase sync. For plant parents who want to keep things alive without becoming botanists.

Sites I've shipped.
Custom websites for indie projects and for clients. Same care, different medium.
A short version.
I'm an iOS engineer based in Madrid. Since 2017 I've been building Metrociego, an app that helps visually impaired people navigate the Madrid Metro, now past 8,000 downloads. By day I work on Meteosat satellite data at GMV. Alongside that, I ship my own apps (Leisurist, Greenie) and build custom websites for clients.
