First Crystal
Website, March 2009. Features: PayPal integration, custom CMS, AJAX.
This was an ecommerce site for a local jeweller wishing to make a foray into the world of online selling. The site features a feature-laden CMS backend, coded from scratch by yours truly. As well as allowing staff to add new products and categories, they can also drag-and-drop to reorder the menu sequence in a nice AJAX way.
PayPal integration posed the challenge of encrypting payment buttons on the fly, but with some clever caching this was automated so the site administrators need never get their hands dirty with PayPal's less-than-straightforward documentation.
I used jQuery to provide a feature typical CSS can't quite achieve - equal height containers. Each box containing a product is size matched for a consistent, grid-based design.
