Build the backend of an App

I need somebody to code a backend for an App. We will use a JSON integration, and I need some functionalities:

1 - logging everything (a method to log some user interactions)

2 - reading from an external google sheet document a list of questions (1000 questions).

3 - serve one question at a time for a specific user

4 - maintain the last question served, checked if the answer is correct or not, advance to the next one.

5 - keeping a track record for every user, and being able to provide the correct questions, incorrect one.

6 - report every action of our users.
