yashaswinim191/Application-Portal ? reverse-engineered prompt

Build me a simple employee application portal where people can sign up, log in, and submit their details, and where an admin can log in separately to view, review, edit, and delete records. I want the site to feel clean and easy to use, with a React frontend and a Node and Express backend connected to MongoDB.

Please make authentication secure with password hashing and token based login, and protect the admin pages and API routes so only signed in users can access them. The app should support storing application data safely, handling resume uploads, and showing useful success and error messages. Keep the frontend and backend separated, and make sure they can talk to each other properly across local ports.

If you need to check current docs for any setup details or best practices, go ahead and look them up online. I mainly want a working full stack app I can run locally on Ubuntu with a clear login flow and basic admin management features.
