I'm an experienced Windows Phone developer with experience from wide variety of app types including but not limited to entertainment apps, data heavy apps, cloud based apps, games and technology demos (for example synthesizer). I can pride myself with knowing the platform in and out because of all the different projects I've been working on so the quality will be top notch and I can easily provide you with apps that get certified and added to the marketplace quickly.
Since I do programming and graphics work side by side I can basically do everything from the planning to asset creation, documenting, teaching, optimizing and releasing (although I guess that you want a package that you'll then submit to the marketplace). I also know the platform so well I can easily explain the techniques I've used in detail. I also have extensive knowledge of the Visual Studio and .Net Framework (mostly C#) in general so you'll be in good hands.
In case you're interested I can provide you with some examples of my work related to this area since there's none in my public portfolio.
