I built the Union Theology e-resource site.
The site features 300 articles with a mixture of text and audio, organised into a searchable category system. Visitors to the site can register and fill out a profile, which gives them the ability to save resources for later reading, and also view curated collections of articles.
The content management system makes it easy to add new articles and add them to categories.
Audio is stored on Amazon S3, and presented using a HTML5 audio player with a custom skin.
The site is responsive with three sizes - desktop, iPad and iPhone.
