I'm looking for someone to develop an Amazon Web Services hosted API to facilitate the creation of photo displaying apps. The API would be accessible to client applications on several different devices. The API should be RESTful in its implementation.
Developers consuming the API would have the ability to, with the right permissions, add photos to a collection, delete photos from a collection, etc. I would need it to handle user and their associated permissions. The API would need to handle storing the photos intelligently and in a few different sizes.
You are free to write it in either Java, PHP, or Ruby. Whatever you use I want it to be hostable on AWS.
