Firebase Authentification - Angular Node.JS

Bonjour à tous,

We'd like to quickly implement a email FireBase authentication to our Saas medical website with two different population on two separate database :

For patients : email /phone number / password
For doctors : email / phone number / password / id photo upload

Basic front-end & back-end required.
The website is working with Angular/Node.Js

We will give you a source code to simplify/accelerate the implementation.

Starting as soon as possible (today or tomorrow)
Experienced dev required.

Thanks !
