Amazon Mobile Site Redesign

Redesign of the mobile website. I did the 2009 redesign of the site targeting iPhone, Android, and other smartphones. I worked with the mobile product manager and executive staff to determine the goals of the redesign. I reviewed hundreds of customer feedback emails and performed my own heuristic evaluation of the existing site to help inform these goals. I was responsible for all aspects of the design including information architecture, interaction design and visual design. I also conducted several rounds of usability testing with paper prototypes to validate the design before it went into development. As of October 2012, this design is live and continues to be refined and extended.
