Backend Developer Challenge

Build a system that will accept a multipart form upload while displaying a percentage progress

Specification

When a user picks a file from their computer, the upload automatically begins. While uploading the % complete is visible on the page. It should atleast update the status every 2 seconds. Please ensure the progress bar works in a range of browsers including IE8.

Please try to avoid too many libraries for the task, unless required

Backend Developer Challenge

The challenge proposed here is to build a system which acts as a socket server, reading events from an event source and forwarding them when appropriate to user clients.

Clients will connect through TCP and use the simple protocol decribed in the section below. There will be 2 types of clients connecting to your server: -

1 event source: - It will send you a stream of events which may or may not require clients to be notified.
Many user clients: - Each one representing a specific user, these wait for notification for events which would be relevant to the user they represent.

Please try to avoid any unrequired code libraries for the task, unless specifically required

Please find my solution below:

1. I propose to use an MVVM based application architecture.
2. for iOS I would recommend data binding (View to ViewModel) using RxSwift for a sample implementation by myself click here.
3. for Android I would propose Data Binding with my own helper library. Rest of the document would only focus on an iOS solution.
4. As for code organisation, we can use an use-case based folder grouping.
5. We should also separate our classes into Entities, Domain Services, Application Services, Repositories and Network layer.
6. the RESTClient should be a singleton, sample [implementation here](https://github.com/aprofromindia/Yahoo-Weather/blob/master/Yahoo%20Weather/RE
