Develop Angular 2 Blogging Web App.

Develop Blog posting and commenting application using Angular 2 HTML5 Bootstrap with infinite scroll ( blogs keeps appearing as one scrolls down until no more blogs in database). Blogs that may contain, images, tables etc. are assumed to be stored in MySQL. You must have extensive Angular 2 experience with open source or commercial Angular 2 based applications that you developed and well versed with build tools for development and production builds, testing and deployment. (webpack, jasmine, angular-cli). Each functionality should have jasmine unit test. The backend to be based on Groovy/Grails which simply provide JSON RESTful web services. If you do not have Groovy Grails experience I can consider NodeJS backend. I am looking for very well designed web app with nice and elegant layout. Bellow each blog users can leave comments for that blog. Each comment can be replied to by another commenter if the user chooses reply to option for a given comment which in turn can also have reply to option like a thread of conversation with a nice layout.
