sahelisingharoy4/JobPortal-MERN ? reverse-engineered prompt

Build me a simple job portal app from this project. I want a clean React site where job seekers can browse a list of jobs, search and filter them, open a job to see the details, and apply through a basic form. I also want an employer side where someone can add, edit, and remove job posts, so it feels like a real job board instead of just a static page.

Keep the design modern and easy to use on mobile and desktop. Connect the frontend to the backend folder so the data comes from real API endpoints, and use the existing env files for configuration. If anything is missing, set up sensible defaults and leave clear placeholders where I can plug in auth, database settings, and deployment later. Please make it work cleanly in this Vite React project, and look up current docs online if you need to.
