Build a MEAN item directory site with cms

I'd like additional development done for an existing MEAN stack app developed using Node.js, Angular 1.3x, and Mongo DB. It currently lists items by category and the user can login, but I'd like to add the following functionality: - user can login using facebook - users can upload images / videos - user receives a welcome email after registration - user profile page - deep link the items by category and page number - user can share an item on facebook, twitter or save to their favorites - restrict the admin area to only the admin
