Bonjour,
Sorry, its only word (and croissant!) I know from french, I hope we can communicate in English. We are agile team, we specialize from 2010 on Javascript (MVC, POO, Backbone, NodeJS), we work with all the technologies you've mentioned, HTML 5, CSS 3, Symfony 2 (PHP), Linux, Apache, Build (Gulp), Git, Puppet, Capistrano, Jenkins. We based in Ukraine/Montenegro (partly), if it will be necessary - we can visit your office and who knows, probably we can stay there if it will be really necessary
Looking forward to your reply,
Best wishes,
Barbara&IQRIA team
