Hi, I'm François Best

I am a developer, an open source lover and a writer from France.

This is my digital garden, where I write about the things I'm working on and share what I've learned.

About Me#

I live in Nancy (France), but my heart belongs to Grenoble, where my wife and I met and plan to settle in the near future, with our first child on the way.

I love cycling, both for transportation and tourism. With my friends, I've toured across 7 countries on my bike, along the French Atlantic coast, in the Alps and in the Balkans:

We rode 1010km, 11697m of elevation, for 65+ hours, across Albania, Montenegro, Bosnia and Herzegovina, Croatia, Slovenia and Italy.

This is a screenshot of a progressive web app I made for us to track our journeys, it's called Stravels and allowed us to stitch together our Strava activities onto a map.

Arturia

2010

I helped design the MiniBrute analog synthesizer when I was an intern at Arturia. It was my first professional experience and a lot of fun.

I had the privilege of working with a great team led by Yves Usson, from whom I had learned analog synthesis before joining Arturia.
