The project was created under NDA and I cannot share the details about the contractor, but the link details some general information about the projects.
InstaSize (Development)
InstaSize is still the original and easiest way to post entire photos on Instagram without cropping. We’ve just added a few more features that will make your photo’s that much better.

* The app allows to post entire photos on Instagram without cropping
* Photo editing features – filters, overlays, scale, crop, etc.
* Use of multiple Nokia Imaging SDK filters (several custom ones)
* Windows Azure services integration
* Advanced Memory Management – the application requires significant amount of memory during rendering as it can create images up to 2048x2048px size.
* Custom UI Elements - several UI controls and animations had to be created specifically for this app
