saiful-aj18/findback-bd-mern ? reverse-engineered prompt

Build me a full stack Lost and Found website for Bangladesh called FindBack BD.

I want people to be able to sign up, log in, and then post lost item reports or found item reports with photos, details, category, location, date, and status. Users should be able to search and filter posts easily, open a post to see the full details, edit or delete their own reports, and contact other users through chat. Please also add notifications for new messages and item updates, plus a simple admin dashboard where an admin can manage users, reports, and see basic platform stats.

Make it look modern, clean, and fully responsive on mobile and desktop. Use a React frontend and a Node and Express backend with MongoDB, JWT login, image upload support, and real time chat and notifications. If you need to check current docs for anything, go ahead and look them up online.
