I have several years of experience in ASP.NET development. The most recent works that I have done is for the site jogg.se, where I have been involved in feeds, image upload functions, GPS data import, article management and lots of other things. If I should pick a favorite thing I have done there I pick the Running Calculator (in Swedish). Try it! (If you understand the language...)
Other ASP.NET projects I have built is a requisition management system and a system for automatic generation of price lists/product brochures for Ascom Sweden.
