This project is a production-style Order Management System API developed using ASP.NET Core Web API. It focuses on real-world backend engineering practices rather than basic CRUD operations.
The system handles complete order lifecycle management—from creation to fulfillment—using structured state transitions and background processing. It includes asynchronous job handling, logging, retry mechanisms, and integration-ready architecture.
Order lifecycle management (Pending → Paid → Shipped → Completed) Background job processing for order handling and notifications Payment simulation with success/failure flows Inventory management with stock validation JWT-based authentication and role-based authorization Centralized logging and global exception handling Clean Architecture with separation of concerns
This project is designed to demonstrate how scalable backend systems are built for real-world commerce and automation scenarios.
