The task's backend is built with Laravel 5.7 using PHP version 7.1.3.

To install backend dependencies, run composer install in the root directory. Afterwards, set up the database values in the .env file and then run migration using php artisan migrate. To seed the database, run php artisan db:seed

This task uses clean code by employing request - validation - controller - service - repo - model at the backend where possible. I utilised Laravel's dependency injection.
