Develop mobile comunication with database (Unity3D)

We are a Mexican foundation that makes free learning games for kids, we mainly use the engine Unity 3D and this project is all about working with Unity. Players have to register in our portal ([login to view URL]) and then can play freely to anything they want, but we recommend games based on their performance. Our games send to the DDBB gameplay information using JavaScript. That information is then processed by an algorithm that tells us how well is the player doing. In short: We collect gaming performance information and then our algorithm recommends what should should be played next. We are moving from web based (Unity web player) to apps, so we need to move from JavaScript to web services and we need the games to manage player sessions and be able to make game recommendations like we do on the web. We already have 5 games that are working fine on Android, but we are not happy with the current provider, we need to speed up this and we have nearly no documentation . This project briefing would be: - Provide a unitypackage that contains the resources for the player session management. (should work with Unity 4 and Unity 5) - Provide the documentation to help our developers go from JavaScript to web services. - A system that can store locally the player info and gaming data when the device is offline. What we can provide: - Support from our DDBB developer - Existing betas (not documented) of this system working (not exactly as requested in this email) - All art required. How we will manage the project and other details - We can deposit in freelancer any ammount agreed to be paid. - The money will be released based on milestones - Automated bids will be ignored - We need code to be commented, documented and we will review all of it - We need a dev that can keep working with us, and that gets to know our system, so can jump in again often.
