Database and APIs to collect and further process users results -- 2

I need a database in Mongo. Most probably 2 tables of 8 fields maximum each, pivot between them, 1-2 queries and two APIs to pull and push data. You will have access to the server to install it and test it. Clear instructions will be sent after the bid. Due to many problems here with fake freelancers, I will not sign any contract until I see the database functional on your machine. The payment is released after successful deployment/test on my server. Knowledge of Telegram API and Python is an advantage. In case you are a full-stack developer we may continue with others.
