Drupal is a free and open source framework and content management system for websites. It is one of the most widely-used frameworks for websites, and it has been used in a wide variety of applications -- from blogs to large commercial and non-profit organizations to political campaigns. Drupal was designed to be easily extensible through the use of "modules", which are kind of like building blocks that can be added to websites to change their appearance and functionality.
This site was created using Drupal. I have years of experience building websites with Drupal. Several of the Drupal sites I've created are showcased on my portfolio listing page. I provide Drupal-related services and can help develop your website.
