This project implements a backend service responsible for managing product inventory, stock levels, and availability tracking. The focus is on designing a reliable system that can handle concurrent updates, maintain data consistency, and support integration with other backend services such as ordering and payment workflows.
Inventory systems must accurately track stock levels while handling concurrent updates from multiple sources. This project explores how to design and implement an inventory service that maintains consistency, prevents overselling, and supports scalable read and write operations in a distributed backend environment.
