About

I build things

Software, hardware, companies, and occasionally furniture. I'm a pilot, a sailor, a photographer, and a perpetual tinkerer. French, living in California.

Flying

Private pilot since 2022, flying out of KSQL (San Carlos). Still amazed every time the wheels leave the ground.

Sailing

Beth and I sailed to Mexico in 2018. I built ChartedSails to analyze sailing data — big data for small boats. I also built KBox, open-source boat electronics.

Open Source & Hardware

pi-blaster (850+ stars) runs hardware PWM on Raspberry Pis worldwide. KBox is a boat NMEA gateway. voodooprivacy sets up a VPN on EC2 in one click. 97 repos and counting →

Photography & Video

I've always loved photography — from street scenes in West Africa to wildlife in Southern Africa. I also shoot drone footage and sailing videos. Photos & videos →

Writing & Speaking

Wrote one of the first French books on iPhone development (2009). Spoke about Rust on embedded Linux at EOSS 2024 and ham radio builds at Pacificon 2014. Gave many talks for Pebble at conferences worldwide. See all talks & writing →

Ham Radio

Built the Minima, an Arduino-based HF transceiver covering 0–30 MHz for under $100. Presented it at Pacificon 2014. Build log with photos →

Embedded & IoT

Rust, Linux, NMEA 2000, Raspberry Pi, Teensy, Pebble watchapps. I like things that run on small computers and talk to the physical world.

I've been building software professionally since 2000 — mostly at the intersection of hardware, developer tools, and mobile.

My first website went online in February 1997 on Mygale — I was 14, writing about Delphi and Warhammer 40k. Three years later, I was asking Usenet for help installing Debian on a Sony Vaio, which became my first technical howto. Then came sarfata.org — thoughts on Bowling for Columbine, C++ compiler trivia, and an altern.org email lost to time.
