Question

Android

What is the best use for developing a backend for an android mobile application from scratch? The application will consist of 80% of the map, the number of screens max 5-6. Requirements: 1) Scalability (there will be a large load on the number of users, but sessionally) 2) The most important thing is to implement the Google places check-in function 3) security 4) reduce the amount of necessary Internet traffic
I also need an admin panel for the application and integration with WEB is possible.

Answer 1

1. It is best to use ready-made Backend-as-Service.
   
2. If for some reason you want to do it yourself, then use the web development tool that you know best (if you are a developer) or your employees (if you are a customer). The quality / price / scalability of the result does not depend on the language or database, but on the ability to use them
   

Answer 2

Golang is a very easy to learn language and at the same time very powerful, it is a pleasure to write backends on it, moreover, if you are a mobile user.
