Need [login to view URL] experienced developer

I need somebody with good (at least 6 months) [url removed, login to view] experience across all of Android, iOS, WinPhone and Windows ..

Some details are as :


We require a custom control that displays a countdown in hours, minutes and seconds, that

optionally makes a ticking noise, and that continues running even if the app using the control is

backgrounded. To be implemented using C# and [url removed, login to view] .

The Detail (If you have any questions, or if you think anything is contradictory

or impossible, please ask)

We require a CountdownTimer control to be developed using C# and [url removed, login to view] 2.x (latest

stable release). This control should work on all [url removed, login to view] supported platforms, excluding

WinPhone 8.0 Silverlight), so should work on Android (including Amazon Fire), iOS, Windows (8.1),

WinPhone (8.1) and Windows UWP.

The CountdownTimer can be running or not-running at any time. If it is not-running, it simply shows

the value at which it was last stopped (or the initial value if it has never been started). If it is running,

then it counts down from its original value down to 0 hours, 0 minutes, 0 seconds, updating the

display often enough to ensure a smooth display to the user, but without wasting CPU (whilst in

foreground, this probably means every 0.5 seconds, but see below for backgrounding). The value

shown will use the appropriate format for the locale settings that the user has configured on the

device. For example, in the UK, this is likely to be hh:mm:ss format, so if counting down from 50

minutes, the value displayed would start at “00:50:00” and finish at “00:00:00”.

To support keyboard usage on Windows, the CountdownTimer should be able to accept the focus.

Tapping or clicking on the CountdownTimer should result in an appropriate event being fired, and if

the user has set them, a Command handler being fired with CommandParameters. It is likely

(although this is up to the developer) that the CountdownTimer will be based on a

[url removed, login to view] in order to implement these requirements. However, no margin or border

should be displayed – whilst a Button may be used, it should appear as if it were just a Label.

Note that tapping or clicking on the CountdownTimer does not stop the countdown, although a fired
