The developer should have experience working with both the android and symbian OS'sas we need the application developed on both platforms, then eventually on BlackBerry.The applicant should have a portfolio of these working applications. To start, a login/logout screen will be required. So you will have to pass the username and password via a connection to a server where existing code will validate the input.On a successful response, a menu of services for that account is displayed on the screen.Each service will have its own user inputs which when passed to the server, will once again trigger existing code and further db access. Each of these phone data inputs will generate a response from the server which will dictate which screen to then display.There will also be testing and subsequent bug fixes.
