Todo: add something cool and smart.


Julien Viet leads product development of eXo Platform’s flagship eXo Portal product on which the entire eXo product line is based. In June 2009, eXo Portal was merged with JBoss Portal to create GateIn, which Julien now co-leads. In this role, he is deeply involved in GateIn’s technical vision and plays a key role in product development and advanced R&D architecture prototyping.

Prior to eXo, Julien was an engineer at JBoss, where he founded the JBoss Portal project in 2004. In four years, Julien built an enterprise-class portal server with a team of only five developers. He started contributing to the JBoss project (application server) in 2002 and joined JBoss, Inc. two years later.

Julien is passionate about open source and active in standards groups. Julien is also an expert group member for several Java specifications, including Portlet 2.0 (JSR-286), Content Repository for Java Technology API 2.0 (JSR-283) and Portlet Bridge for JavaServer Faces (JSR-301). Julien holds an engineering degree from Institut National des Télécommunications, one of France’s top schools for engineering.
