shivam78766/employee-management-system ? reverse-engineered prompt

Build me a full stack employee management system with a clean, responsive interface.

I want users to be able to sign up, log in, and stay protected with secure access. Once inside, they should be able to add, view, edit, and delete employees, search employees easily, and filter them by department. I also want a simple way to manage departments too, including adding, editing, viewing, and deleting them.

Please include a dashboard that shows useful employee stats and a few charts so the data is easy to understand at a glance. Use a modern React frontend with a Node and Express backend, and connect it to MongoDB. Make sure the app uses JWT based authentication and password hashing, and keep the code in modern ES6 style. The frontend should feel polished and work well on both desktop and mobile. If you need to check current docs for anything, go ahead and look them up.
