You have chosen to sponsor your bid up to a maximum amount of .
I need you to develop a web application.
Not php etc.
You should also use the W3C Widget Packaging specification.
Here it is: http://www.w3.org/TR/widgets/
The web application will have 2 pages.
A login page where the user will be able to enter a username and a password.
Then after the user presses the Login button, some data will be fetched from an external API and will return an array via a json_encode($arr).
The data that the user will see in his screen after the login will be based on the current date and the array that was returned.
There will also be at the top of the web app 2 buttons one at the left side and another at the right side to navigate to the past dates and the following dates and then the relative data from the array will be displayed.
There is not need to create a local DB or anything else. The data will be fetched each time the application starts.
The lowest and quickest bid will be mostly considered.
