hi, i'm kevin.

A plush bear you can actually have a conversation with.

Real-time voice, a 3D character that reacts while you talk, and a memory that gets to know you. It reached the top 50 in Entertainment on the French App Store.

Before Ted we put an AI on TikTok Live and let it host its own stream, for hours at a time, with nobody driving.

It landed in the top 1% of TikTok Live, and the gifts people sent it were real money. Watching an audience come back for a character rather than a chatbot is the whole reason Ted exists.

My bachelor thesis: a rack of Raspberry Pis for testing what happens to a mesh network when the radio conditions get bad. Along the way I found a way to jam an entire Wi-Fi network, by accident.

Buy now, pay after harvest. Farmers pay for seed and fertilizer months before they earn anything, so we built the credit for it, scored from open banking data. Company number two, started in my second year at Polytechnique, and it won $25k from Initiator VC.

A proof-of-stake cryptocurrency written from scratch in C++, chain and all, rather than a token on somebody else's. The peer-to-peer layer and the block synchronization were my end of it.

I spent a summer writing code at the company that builds France's nuclear submarines and warships. The job was making a program keep a secret from the computer it was running on.

My school kept timetables in one place, grades in another and clubs in Telegram groups. With friends we built an app that put them together: schedule, homework, clubs, and reviews of the courses themselves. About 80% of the program ended up using it.

My first Android app: it works out when you have started driving and puts your phone on do not disturb without being asked. It shipped under MIZIX, the first company I registered, at 16.

I kept losing USB keys, so I built one that yells at your phone when you walk away from it.

An Arduino Nano and a Bluetooth module in a case around the stick, and an encrypted folder on the drive, so losing it anyway costs you the hardware and nothing else. Then I wrote and filed the patent myself, down on the form as my own attorney, because I was 16 and did not know you were supposed to hire one.

Bluetooth gives up at about ten meters. This one carries it a few kilometers over radio instead, and it got a patent too.

A robot that fed my hamster, with an app to go with it. First thing I made that something else actually depended on.
