Guillaume is a French developer, currently the technical co-founder at NeonMob, a growing online collecting platform running on Django with several tens of thousands of active users. He's been a Python enthusiast for many years, and especially enjoyed using it while being an HCI researcher, to prototype new means of interaction with experimental hardware. If you see him, ask him about how he started an open-source browser based game with 20 children under 17 years old who had never programmed before!
