We have an existing mobile application calling data via .NET Webservice API connecting to MS SQL but we are looking to partner with [login to view URL] as an OEM we need to integrate to [login to view URL] platform. We need some one with the ability to program in [login to view URL] to allow our mobile app to integrate to existing Org and New Org. This means this individual will need to package the program to deploy Org with the necessary objects and build webservice API for the mobile app to connect to for Activities/Events. We only need help on the [login to view URL] / [login to view URL] side.
