EXT JS, .NET 4.5, C# , MVC 4, Amazon AWS, 1-2 days pw

I need a freelance mid - weight developer to come onsite in Leyton for approx 1-2 days per week. The developer will be assisting with the ongoing build of an online game for one of my long term clients (based on a very successful product). Client is keen to push forward with development so there will be room for providing more working hours in the future. This is a nice reliable income for the right developer. The project is very much in early stages prototype so it shouldn't be too much to pick up and you will be receiving my help and assistance in requirements determination, project management and systems architecture.
