Mobile App Developer · Founder of Hopopop

I'm a mobile app developer based in Paris. I hold a Master's in Information from the University of Bordeaux, and have worked with companies like Floa, Cdiscount, and Finzee before launching Hopopop.

The idea came from a personal frustration: I noticed social media was gradually eating away at my attention, and I could feel my brain getting duller. Instead of building yet another screen time tracker, I spent a long time testing different approaches on myself, my family, and friends — looking for what actually changes behavior. The answer was meaningful friction paired with something genuinely stimulating.

That's why Hopopop asks you a challenge before unlocking an app: mental math first, then general knowledge questions, and now world geography — topics I personally find motivating and that work well as a friction mechanism without feeling like a punishment.
