My greatest project has been the continous development of CMS Webstruct, which is a framework and a CMS written in that framework that together form the basis of all our websites. For more information on CMS Webstruct, please contact Crowd Surfing, the company I work at.

All these websites use Webstruct and I have extended the default capabilities with extra content types such as projects, products and discounts.
