We already have a database driven website and a mobile app interface (mocked up) . We need someone who is fantastic at creating the mobile apps backend and integrating this backend with our website technology. The person must have a strong track record and should be able to show us his/her portfolio of mobile apps.
The person would need to recommend what platform to use to create the app. We need the work completed asap! The best skill set, speed to develop, and cost will win. Thanks.
