How to properly implement aggregation in MongoDB?

Question

PHP

Hello!
For the third day I have been puzzling over aggregation in MongoDB.
I have a database of analytical information based on visits to the subsites of our project.
Something like this: https://gist.github.com/RomanGorbatko/ac876f44d2b5...
This raw information needs to be processed by several groups and projects.
I don't want to describe all the pain and suffering. That's why I'm turning to you, Mongo Aggregation Hero! If you are reading this post, please respond! Half the kingdom and a daughter in addition for solving my issue (we will agree on the fee)!
