What is this?
Capstone overview: build ShopNest e-commerce API end-to-end — customers, catalog, cart, orders, payments, refunds, feedback.
Why should you care?
One deployed multi-module API on GitHub is worth more than 175 lessons without a finished project.

What happened?
- Follow the practice steps below on ShopNest.API — typing code yourself is the fastest way to learn.
Try it yourself
- Clone or create solution structure.
- Complete modules in order: Customer → Product → Cart → Order → Payment.
- Add Swagger + JWT + README with architecture diagram.
- Change a route URL or DTO property and save — test again in Swagger or curl.
- Return the wrong status code on purpose (404 instead of 200) and see what the client shows.
