MarketLine Advantage
An ASP.NET MVC application and an early fully responsive HTML 4 design. Built by a small team, this site was a complete replacement, back-end and front-end of a previous incarnation. As the business model was extensively XML the standard MVC views were handled using a XSLT view rendering engine.
My personal involvement was predominantly in XSLT transforms, Javascript and all front-end work including the responsive design.
