I ve done a project at Multimedia Business Services Orange (part of France Télécom) as a freelancer for http://dataflow.be/[2] in Bordeaux France from october 2010 until april 2011.
The goal of the mission was to introduce drupal in the company and transfer all my drupal knowlegde to a team of developers while building an extranet application using drupal.
Ofcourse the extranet application cannot be shown because it is an internal client application.
