One of the more interesting customization jobs that I’ve worked on was one that I did for AfricanCartel.com – it was interesting because I had to do some customizations to the Listings theme that I built for WooThemes. I added a custom slider based on SlidesJS, as well as a page template for Art, but the most intriguing part was the e-Commerce customization that I made. I created a class that modifies the WordPress media library slightly to allow the user to assign a product from the e-Commerce plugin to an attachment – not a post like most e-Commerce plugins work – and all using built in WordPress filters and actions! 
Awesome work you have done, can’t wait to cut my teeth in understanding and speaking php
