Technologies used:

1. NodeJS
2. Express
3. Redis
4. Bull
5. NodeMailer

To run the project, you should create a .env file at the source, with the following attributes:

MAIL_HOST = 'yourHost'
MAIL_PORT = 0000
MAIL_USER = 'user'
MAIL_PASS = 'password'

REDIS_HOST = 'yourHost'
REDIS_PORT = 6379

I also applied the bull-board middleware on the server:

GET - /admin/queues
