Drupal is probably the most popular Content Management System (CMS) on the market, with its popularity creating a large and active community of users and contributions, making it a cost-effective and well-supported platform. It's used to power high-profile sites for organisations such as the US White House, NASA, Digg, Harvard and even McDonalds.

With a number of years Drupal experience and having worked on some high profile sites for some big clients, I have an in-depth knowledge of the platform with extensive experience developing Drupal websites - including custom module development and theming. It's because of this experience that it is is my CMS of choice - and much more, as its usefulness extends to its benefits as a platform for the rapid development and deployment of web applications.
