lokdon-v1.0 for Android secure text

Looking for: Developer, Marketer, Sales person
Standalone System:
 
You will notice that I have a product called LokDon for android but now I want to meet the Windows and Apple market needs and with modification to effect the android in version 4+. This will also add the 'cIoud' modification aspect like www.boxcryptor.com. I have had demands from these users and now is the time to get this accomplished. I am looking for a developer/designer/programmer with a strong background in mobile apps. This person must understand the requirements for both windows and apple applications. 
 
The developed application must work seamlessly in all platform's devices as well. Only seasoned and experienced developer need to apply for this project. We are looking for skills like java, objective-C, C/C++(debian devices), .net (visual std) and C#. Xamarin and Android native is really preferred for scalability and no-frills management. I will have some inbuilt security to stop multiple download from all application stores.
 
You must download LokDon and boxcryptor Android version on your phone if you want to competitive for this bid. If you are very well versed in coding I will make this very easy for you but have to know how to design things on you own tho. Please send me your skype Id if interested.
