Build an Instagram Web Application using Javascript, HTML5, CSS3

Skills needed:- Javascript, any JS library, HTML5, CSS3, AJAX, Node.js, MongoDB or any suitable DB. Task Details:- I would like you to build something like an Instagram Web UI. You can build a little web app. I am not looking for the volume of work. Here are the things which i am looking to get out of the exercise: 1) I want to get a glimpse of your thinking behind data design 2) I want to see how you build few APIs. 3) I want to understand how you approach single page apps 4) I want to see your CSS/UX chops 5) I want to look at how you architect and think of master/detail, CRUD etc. You will obviously see that there is tagging people, messaging, commenting, liking, following, followers etc. Building all of that is not necessary, also building logging and securing everything is not necessary either. I just wanted to use Instagram as an example of a nice UI grid, with good animation effects, having master-detail relations and needing to think through post schema, CRUD, Images etc. Deploy the code at some place like Azure Websites, Heroku etc. Also, you can keep the code in GitHub and make incremental commits. Please let me know if you have any questions..
