Following the buyout of ECHO Interactive by France Telecom/Wanadoo (now Orange, France's leading ISP) Guillaume was part of the team responsible for search engines at www.wanadoo.fr and www.voila.fr (French leading portals). He set up the Wanadoo Portals Quality Team, to improve the performance of Wanadoo's portals, websites and ecommerce sites, where he gained extensive experience testing web applications before moving to the UK and joining a new startup dedicated to web testing (stress tests, monitoring tools, accessibility tests) where he worked as lead developer with some of UK’s blue chips such as T-mobile, National Savings & Investments and web agencies (ThreeSixty).
He joined blue-infinity early 2006 to work on the internationally praised cocomment website. He is now managing blue-infinity's Open Source Practice. His team works principally on large intra & extranets, web applications and websites for leading multi-national companies.
