RokGallery
RokGallery is a ground-up revolutionary gallery extension, developed to be hugely flexible, versatile and user friendly. The system itself is built on a custom tag-based architecture with the ability to have multiple tag-based galleries. RokGallery uses design and concepts that have been traditionally reserved for platform-native applications. RokGallery is available both as a Joomla! extension and as a WordPress plugin.
I worked on the Joomla! version of this extension with other members of the Rocket Theme team and was responsible for writing the Joomla! module and porting the entire extension set to WordPress.
