Built a production-ready checkout and inventory workflow for a live e-commerce store.

The system validates product pricing and stock on the server, manages product variants, updates inventory after orders, supports shipping checks, and connects the customer checkout flow with day-to-day store operations.

My focus was not just on making the checkout look good, but on building reliable business logic that works for real orders and real inventory.
