I work to simplify things, making them easier for people to use and understand. To do this I work in a User Centred way.
I've had many job titles over the last 17 years, Interaction Designer, User Experience Designer, Information Architect, Graphic Designer.
I prefer just to use the term Designer. The scope of the others are helpful when trying to define roles in a team, but often the limit peoples ownership (and responsiblitiy) for the products and services they are building.
In the past I have worked with client such as HM Revenue & Customs, Virgin Money, Nando's, J.K.Rowlings' Pottermore, Visa, Channel4 and National Rail Enquiries.
