Idea for a React Redux more big project

I created two projects, small, an example of Blog (to test mongoose, node, passport, ejs) an App made with React, really small (take advantage of the API API OMDb) look for a title of a film or TV series shows you basic information, nothing of that, for a project with React Redux I would like to try something bigger, I would like to create a bee to register users and the various parts of the site and then use React Redux for the Client side, I have a series of videos made by a person who creates a social network, very nice but I would like to do something different, I always do so when I follow video, I take inspiration from what they do to do something of mine, any ideas?
