I am currently the Lead Backend developer at Drivy, a startup creating the leading european peer to peer car rental website. Before that I worked both in France and the US for various startups, agencies or larger companies.
The rest of my time is spent giving classes (at HEC, HETIC, Learn Assembly, FACE and more), talking in meetups, contribute to open source or working on side projects such as Liff, a quantified self app to track your day in a relevant way.
