I know that you only have one controller, but I don't think it's wise to reference each and every controller in one single angular.module(...).controller() declaration... Perhaps read this: https://github.com/gocardless/angularjs-style-guide

Also, it might be worth looking at ng-annotate so you don't have to specify the array of dependencies. It's not necessary but it does help speed up development a little bit, not having to type that out all the time - it can get quite unruly sometimes. :P

Further than that, you need to implement unit testing, as well as end-to-end testing with Angular Protractor. I've been on a large scale Angular project without any testing in place, and boy did I give the lead my two cents about how much trouble that caused us. The project was delivered 2 weeks late because of buggy, untested code. Prevent this as soon as you can.
