I've been working as Art Director for eBay / Tradera the last 4,5 years. During this time I've been working with design, UX, marketing material, front-end development and apps. The designs and features have been tested with A/B-testing and focus groups all to increase conversion and UX.
A year ago Tradera began to work on a responsive site and that has been one of my top priorities since then.
The mobile/responsive web project has not been focused on that much design yet. The first part has been to get the functionality up and running because it's built from scratch. There are alot of new designs but I cannot show them here since they have not been released for the public yet.
