User Roles, Authentication Fixes & Workflow Error Monitoring

Two related pieces of work on our existing web application and automation layer. 1. Authentication and user roles - Fix the backend logic for creating users. - Add routes for changing a password and updating a user from the admin panel of our web app. - Correct the role-based permissions so each role sees and can do only what it should. 2. Error monitoring - Add a failure-handling workflow in our automation tool that notifies us whenever any workflow fails. Deliverables: working, briefly documented code and a functioning notification workflow. This is a fixed-price project. We are looking for a developer with solid backend and authentication experience.
