I am now working full-time on my apps, and am not available for freelancing. If you have other questions, feel free to get in touch!

Last updated: Aug 21, 2020


I've been developing iOS apps since 2015. Before that, I worked at Google Cloud Platform, Pangea Reality (Deloitte), Yoobic and I co-founded SmileHunter.

I am also a solopreneur in charge of the development, the design and the marketing of several apps on the App Store.

You can find me on Twitter, LinkedIn, and here's my email. I speak French and Spanish.

Apps Portfolio


Lokas is the first app I ever created, and I have been working on it since 2015. It allows users to learn Spanish vocabulary & conjugation in record time, using a spaced-repetition algorithm.


Swift, Firebase, Animations, In-App Purchases, Push Notifications.

2019 Update

I removed Lokas from the App Store and will soon launch a new language-learning app replacing it.

Super Habit

Super Habit is a brand new app I built to track daily habits. It shows your progress on a yearly calendar and computes your current and longest streaks.

In the Press

#2 Product of the Day on ProductHunt with 500+ upvotes.


Swift, Calendar and Dates, Archiving, In-App Purchases.


I originally built Memy in a few days in 2017. In 2018, I redesigned the app and switched to a freemium model with auto-renewable subscriptions.
It lets users learn texts by heart, by gradually hiding words or sentences.

In the Press

Memy was featured by AppAdvice in 2018, which generated 20,000 downloads in 2 days.


Swift, Auto-renewable Subscriptions, Archiving.

Stupid Bros

Stupid Bros is an endless race game in which users need to control two characters at the same time. I built the game to learn about SpriteKit, Apple's technology for games.


Swift, SpriteKit, GameCenter.
