Open Source¶

While most of my coding time is devoted to internal Schneider Electric software, I maintain some open source activity focused on addressing "common" transverse issues. Quality is "best effort given the allocated time".

Footprint¶

Below is the number of packages downloads for my python codes, in million of downloads per year:

I also contribute to other's codes. Below is an attempt to present both activities.
