I am an experienced SharePoint designer and have been involved in projects using SharePoint 2010 and 2007.
Projects include websites, intranets, extranets, custom applications. The branding work has involved themes but also SharePoint master pages, CSS and jQuery where necessary to achieve the look and feel.
I have recently worked for a Microsoft Gold Partner so can assure you that my standard of work is representative of this. My role included being a lead designer as well as a project lead so I am used to working to strict deadlines and ensuring the client is kept in the loop at all times.
Examples of my work can be seen in my portfolio.
