I can see various things that could be improved in the code, and they can be classified in the following areas:
Naming Convention

I know there is all this talk about having only one composition root that set all your dependencies and that you should always prefer constructor injection to other types, but sometimes it just doesn't make any sense for me. Here is my pseudo code :

I like to explicity return function even for void functions to reduce the use of if-elses.
