Build me a full online shop where people can browse products, view details, add items to a cart, and place orders. I want customers to be able to sign up, log in, save their info, and see their order history, and I want an admin side where products can be added, edited, and removed.

Make it feel clean and easy to use on both desktop and mobile, with a simple modern storefront and the basic backend needed to make the app work end to end. Set up the data flow so the frontend talks to the server properly, and make sure the main shopping flow is smooth from product page to checkout.

If you need to look up current best practices or docs while building it, go ahead. Keep the code organized, working, and easy to extend later.
