We need an iOS app that will be delivered via our enterprise app store. Basic requirements are as follows - all are non-negotiable: - Development must be done in Xamarin on Visual Studio - you will be required to deliver source code which can be audited by a third party. Xamarin is mandatory, C# is preferred for the Visual Studio environment. - App must support app encryption on the device - App will use bluetooth to interface with raspberry PI units to retrieve, store, and upload data files - Use of QR codes to "pair" to bluetooth devices would be ideal - iOS devices include iPhones and iPads - Provisions must be made such that future iOS releases are supported as easily as possible - Once data is downloaded from the raspberry PI, data must be stored and then uploaded to a URL for an existing web application. iOS devices will *regularly* not have connectivity (wifi or cellular) and the application must tolerate connection fluctuation.

Hello, Based on the description the project requires the development of a Xamarin (C#,.NET) application which will target iOS devices as iPad and iPhone and it will communicate with raspberry PI devices via Bluetooth. The project requires expertise in embedded devices as Raspberry Pi, security (encryption), Bluetooth, BLE support and development using Xamarin (C#. NET) platform for iOS devices. I am not sure if you also need Android support. We can discuss. I am mainly a C#.NET developer (WPF/XAML, UWP, SQL, Xamarin ...) expert in Xamarin but also an embedded software engineer specialized with Raspberry PI and other single board computers (BeableBone, BeagleBoard, ATOM etc) C/C++, Java, Python. Mobile solutions I build using Xamarin however, for full intergation, a knowledge of iOS and Android are required too . I have been working for several years in banking security where we have been working on cryptography solutions too so I am sure I can develop the required encryption. Regarding the cost and the time to deliver I would like to make a better cost estimation and delivery deadline after we discuss and after I analyze the complete project specifications. It would be good to receive a small document with the detailed project description of all functions. If you are interested we can schedule a meeting through Freelancer.com private chat. Best Regards, Patrik
