Is CI right for me?

Just a heads up message from me. CI will be JUST the right for you Building backends is usually a pain in the ass, but using CI will definately take off some of the burden and you can concentrate on doing(and have fun while learning) instead of figuring out how to do it

prestondocks already mentioned Modular Extensions/Modular separation and you should use it on bigger projects(or even smaller) as you can easily divide your app into smaller pieces and have better organization for your controllers,views etc.

Couple of additions that I seem to be using for every project nowdays:
Using Base controller(s) - From the page: "Base Controllers are a nice simple way to give you global data, logic and shared code which can be specific to a certain part of your site."
Base model - Basic CRUD+more for your models
Ion auth - Simple to use authentication system
