I have been using the Drupal framework for over two and a half years (since V4.6.6, released March 2006). Although I have created a number of sites, done custom theming and coding, including modules, almost all of it has been for internal (intranet) or private projects so there is little to see on the Web.

This Web site was created using Drupal, replacing the earlier site using static HTML pages.
You can read about the modules and themes used here.
Online Database of Humanitarian Aid Supplies and Suppliers
Another early Dupal project was IHAPSNET, an onlne database of Humanitatian Aid Supplies and Suppliers. The project required extensive custom coding, partly as a result of the customer's special commercial requirements but also because of the many shortcomings of the early version of Drupal used.
Online Legal Aid
One of the earliest sites I implemented with Drupal was a demonstrator in support for a regional funding bid for an On-line Legal Aid project in the Balkans. This was created using Drupal 4.6.8 and used the i18n module to provide bilingual site (English and Serbian) and a modified version of the B7 theme.
The bid was not successful and the demonstrator was decommissioned, but a screenshot is attached.
