I need a mobile application which must run on iOS, Android and Windows Phone.
It is a very simple application: the user types a message which will be answered with 3 (three) statuses: no, maybe & yes. The answers should be selected using the traffic light lamps: no - red, maybe - yellow, yes - green.
The message can be sent to every user in the contacts list of the user's phone. Every user selected, will get the message (provided she has installed the application).
Every user who got the message can see what the other participants have answered (red, yellow or green).
A user can send more than one messages and also receive more than one message.
The application must be device centric (there will be no need to log in). This means that in case of switching the SIM card, the application should still as if the SIM card was not switched.
There must be only one code base. I don't want code written specific for iOS and other written for Android and ... .Therefore Xamarin should be used, which supports the three main platforms.
According to my research push notifications must be used. I need a solution which is not service dependent and can work without any service website. Probably there must be implemented a server application to support the push facility. This application should be written in ASP.NET MVC (in case this is a problem I am open to any other solution proposed).
If there is any dbms to be used on the phone it should be MongoDB (I'm open for any other NoSQL database). This dbms should also be used in the server application.
A proof of concept application should be written prior to any main development. I will also need instructions on how to compile, install and test the application.
A detailed description of all the use cases will be provided after assignment.
The applicant should speak and write English without any problems. Development is about to be done in a Scrum-way (so some knowledge about this principle is advantageous).
