Refactor the product quantity/stock to be an atomic and concurrent safe. The current implementation might lead to invalid stock values if multiple requests are made at the same time.

Implement the user addresses feature. This way we can store the user's address and use it in the checkout instead of an hardcoded value.
-
Implement the user's order history. This way we can store the user's orders and show them in the user's profile.
-
Implement the cancel order endpoint. This way we can allow the user to cancel an order if it's not yet shipped.
