Aurélien Hébert is a software engineer since 2015 and loves to work with data. He started in the Alten R&D; team on a Big data project. This project was about discovering pattern in mobility data. After this first experience he wanted to work on a technical project including more sensors data. He joined a Startup (Cityzen Data) building an open source Geo-Time-Series database (Warp 10) and its associated language to manipulate it. Here he got data, a lot of them. He also like to share his experience in local conference such as FinistDev or meetups.
