new social network site like reddit or instagram.

we are trying to build a new social network platform like instagram or reddit that similarly works at this following link : [login to view URL];ts=1494757535400 the main function is basically a place where you can upload stuff and people can comment and like or dislike (up vote or down vote like reddit) but it has to work without reloading the page whatsoever. (refer to the reference site) your main job is to code, but you should be able to explain to us throughly about the coding, and make sure i understand the code and how it works. might have to use django rest framework and angular js.
