Creating an app like instagram : <p>I want to create an application like instagram and I have already created a simple social app on parse which shows user photos. However I want to implement complex functions such as adding friends, viewing friend's feed,etc. I want to know if such an app can be built entirely on Parse or a similar service? Do I need to develop a backend for such an app? If yes, what programming languages should I learn. I'm familiar with android studio, SQLite, JSON, Java. Pls suggest.</p>
