I build mobile apps for a living, and a few more for fun.
By day I lead mobile development at
Partoo, a B2B SaaS
that helps local businesses get found and chosen. The rest of the time I design, build and
ship my own apps from first sketch to store listing: product, design, code, content and launch.
I mostly work in React Native and Expo, with tests and CI from day one, and AI agents in the loop.

Four apps I designed, built and shipped on my own. Swipe the screenshots.
QOTCHA
Party games where your friends twist your answers into traps.
Live iOS & Android · Oct 2026
You answer a secret question. Your friends write fake questions your answer could also fit,
and the whole table votes to find the real one. Four games in one app, one phone each.
Real-time multiplayer: join with a room code, a link or a QR code. The game engine runs on the server, so nobody can peek or cheat.
8 card packs, written in French, English and Spanish (rewritten for each language, not just translated).
Free with no ads. One purchase unlocks a pack for the whole table.
A live guessing duel: find your opponent's secret star first.
In testing iOS & Android
Each player gets a secret card: a footballer, a singer, a movie hero… Take turns asking
yes-or-no questions. The first to unmask the other's star wins, and the other one is
grillé (busted).
Turn-based duels with a 30-second clock, presence, and reconnection handled on the server.
Quick matchmaking, ranked points, a weekly leaderboard and a daily challenge.
1,300+ stars across 6 themes, generated by a script that rejects ambiguous cards.
Hot potato, with a bomb, across your friends' phones.
In testing iOS & Android
A bomb lands on your phone. Beat a quick mission to pass it on, then pick who gets it next.
Nobody knows when it explodes: it could be two minutes, or a whole day. Whoever holds it
gets the BOOM, and a penalty voted by the group.
Asynchronous multiplayer that runs all day. The explosion time stays on the server, never on the phones.
9 missions to defuse the bomb: trace a path, cut the wire, shake the phone, blow into the mic…
Live Activity on the iPhone lock screen showing who holds the bomb. Available in 6 languages.
People are bad at noticing slow change. Photograph a crack, a damp patch or a plant, and Lento
lines up every photo from the same spot, measures the change, warns you when it gets worse,
and builds a dated report for your insurer or landlord.
Guided capture: the previous photo shows through the viewfinder, with an alignment score.
Computer vision (OpenCV) does the measuring. Claude explains the results in plain words, and never makes up a number.
Built as proof: timestamps on the server, a fingerprint for each photo, data hosted in the EU.
