• There are three user roles User (Patient), Doctor, Admin
• User can sign up, open Profile, browse doctors by category, create an appointment, get a recommendation
• Doctor can sign in, open Profile, browse appointments, create a recommendation
• Admin can browse patients and doctors, create a doctor, create a category, assign a doctor to a category, etc

• Appointment should be completed (closed) after a recommendation is added
• Log in through phone_number
• Doctor can have only 10 pending appointments at a time

Tech requirements:

• RoR
• Devise
• CanCanCan
• RSpec, Capybara, FactoryBot, Faker
• S3/Cloudinary for images
• ActiveAdmin/Administrate for admin section
• Deploy to Heroku

Notes:

• There are instances where code could have been much DRYer (took shortcuts for the sake of time)
• I considered thorough phone number validation but figured it's not the point of the task

Things that I'd have added otherwise but skipped due to time/out of scope constraints:

• Hotwire (Turbo, Stimulus)
• ActionText
• ActionMailer
