I was the WEB / UX / UI / Front-end Designer at West One Technology (UK) ltd., and worked in collaboration with the development team on various Microsoft products. I am responsible for the redesign of Microsoft Trade-in Website / Portal by creating Design concepts and research, user flows, wireframes, and visual designs for features of the experiences.
MS doesn't have a fully working Trade-in website in the UK/Europe's region. They had one(3rd party) website but it's outdated and limited functionality.I did attend some phone conferences with Microsoft UK to understand what they really want and they gave me a full set of requirements.
I am working on Microsoft Games Console Website (Trade-in Promotion) at the moment.
