Hello, I'm
Building cross-platform mobile apps from the Canary Islands. 6+ years shipping production applications.
Rank every contest, then play the Daily
Full-stack mobile app for Eurovision fans. Rank every contest back to 1956, duel head-to-head, explore the full results archive, follow national finals, and take on Douze Daily — a new song puzzle every day at midnight UTC, same for everyone, with streaks, monthly leaderboards and an archive of the days you missed.
Medication reminders that stay on your phone
Medication tracker for iOS and Android with local notifications, family profiles, an adherence calendar and home-screen widgets. Everything lives in an on-device SQLite database — no accounts, no cloud, no analytics — and the whole app is localized into 33 languages.
Focus timer with a soundscape you mix
Native Android app where the timer and the ambient sound are one product. Blend up to three of twelve sounds, each at its own level, and the interface — gradient, particles, colour — is mixed from what you built. Session plans, a second mix for breaks, a sleep timer. Two panes on tablets, 47 languages, no network permission at all.
Privacy-first receipt scanner
Receipt scanner for Spanish supermarkets. ML Kit reads every receipt on the phone, a review screen shows the zones it found, and on iPhones with Apple Intelligence an on-device model repairs the bad reads. No account, no cloud. 1.0.0 is in review at both stores.
Products I helped ship, and the role I held in each.
