Back-End Cashier System

Cashier Management System built using ASP.NET Core, C#, and Entity Framework Core. The system implements secure JWT Authentication and Role-Based Authorization to manage user access efficiently. It provides complete CRUD operations for products, categories, carts, and orders, along with an integrated cashier workflow for handling sales and customer transactions. The project also supports discount management for orders, order status tracking, and analytical reporting (daily, weekly, and monthly). The system follows RESTful API standards and clean architecture principles to ensure scalability, maintainability, security, and high performance.
