Bastien Guerry is the free software officer for the French public administration. He first studied philosophy and cognitive sciences. He got interested in the free software movement in the late 90's and taught himself how to program by contributing to GNU Emacs. In 2008, he got involved in the One Laptop Per Child initiative and was recruited by Wikimedia France as its first employee in 2010. In 2017, he joined the "Public Interest Entrepreneurs", a program led by Etalab, the French mission for open gov/data. There he discovered the challenges faced by public agencies when it comes to maintaining and enhancing resilient IT infrastructures, recruiting tech profiles, rationalizing the use of "open source" and the contributions made by the public administration to the larger free software ecosystem.
