I would like to have a simple facebook app wich will include a dashboard for each user.
In the app he will gather facebook credits.
The app must be able to transfer this credits to his account based on our alghoritms.
It must have a DB behind.
It must handle big amount of data and multiple calls in the same time.
It will work like an affiliate program with unique link attach to each account.
more details after i choose you based on your experience with facebook api.
