Technical Demo & Code Overview - Module 12

In this video, I walk through a full-stack Spring Boot backend project: a restaurant delivery system built with authentication, role-based users, and a relational database structure. The application demonstrates real-world backend architecture using Spring Boot, Spring Security, JWT authentication, and layered service design (Controllers, Services, Repositories, DTOs). Key features covered: User authentication with JWT (login endpoint + token generation) Role-based user structure (Customers, Couriers, Restaurants, Employees) Full relational database design with foreign keys RESTful API endpoints for core business logic Order creation and product-order relationships Error handling and secure authentication flow This project is designed to reflect production-style backend development practices and simulate a real delivery platform architecture.
