sonu22957/ShopNest-E-Commerce ? reverse-engineered prompt

Build me a full stack e commerce app called ShopNest that feels like a real online store for both customers and admins.

Customers should be able to sign up, log in, browse products, search by name, filter by category, open a product page, add items to a cart, change quantities, remove items, and place orders. They should also have a profile page and an order history page. The site should look clean and work well on mobile too.

Admins should have a separate dashboard where they can add, edit, and delete products, upload product images, update stock and prices, manage users, and view orders and basic store stats. Use secure login with role based access so regular users cannot reach admin pages.

Please build the frontend and backend, connect them with REST APIs, and store data in a database. If you need to check current best practices or docs, look them up online as you go.
