Raphael joined Odoo in 2011, when it was still called "OpenERP".  He quickly moved to the "Framework" team, where he designed and implemented the "new API" of Python models.  When the team grew, he became the team's leader, mostly because of the lack of other candidates.  He kept contributing many optimizations and bug fixes in the framework.  He regularly gives talks to Odoo Experience, and happily chats with every developer coming with nasty questions or bright ideas. And he also writes down his own Odoo biography, when asked to do so.
