I upgraded the NACLA site from Drupal version 6 to 7. In doing so, I also rebuilt the site's e-commerce (migrating from Ubercart to Drupal Commerce), added new newsletter functionality, and rebuilt NACLA’s magazine and subscription architecture. I provided wireframes for the new site, and then themed it based on client mock-ups derived from the wireframes. The site is fully responsive.
I've worked with the North American Congress on Latin America (NACLA) since 2009.
