About

This is my personal blog. I write about technology, open science and open data. I am involved in a number of open source projects, the biggest are xtensor and xsimd. I also work a lot on technologies in the Project Jupyter space. I did my master studies in Robotics, Systems and Controls and still use ROS on a daily basis.

I am currently employed at a small & very fine software consultancy in Paris, called QuantStack where we are lucky to work on mostly open source software.
