Sylvain came to OpenStack in 2012 with Diablo when he was acting as an Operations manager responsible for deploying a private cloud platform for a SME company where it was used for QA and development purposes. Later on, he changed to a full software engineering position as an ATC for a Stackforge project called Blazar where he implemented reservations as a service in OpenStack and consequently had to interact with Nova and Keystone. He's now a Senior Software Engineer at Red Hat with a primary focus on SLA in OpenStack and fully working on Nova in order to make OpenStack more resilient.   On a side note, he's co-organizer of a local OpenStack meetup group in his geographic area in the center-east of France, called OpenStack Rhône-Alpes.
