+## Features
+
+### Backend (Spring Boot 3.4.1 + Java 21)
+- ✅ JWT-based authentication
+- ✅ Role-based authorization (RBAC)
+- ✅ Password encryption with BCrypt
+- ✅ Clean architecture with service layer
+- ✅ Bean Validation
+- ✅ Comprehensive error handling
+- ✅ SLF4J logging
+- ✅ H2 in-memory database
+- ✅ JPA/Hibernate
+- ✅ SOLID principles implementation
+
+### Frontend (Angular 19.2.15)
+- ✅ JWT authentication
+- ✅ Route guards for authorization
+- ✅ Angular Material components
+- ✅ Reactive forms
+- ✅ RxJS observables
+- ✅ TypeScript strict mode
+- ✅ ESLint for code quality
+- ✅ Proper error handling
+- ✅ Type-safe services
+
+## Clean Code Principles Applied
+
+This application strictly follows industry best practices:
+
+### SOLID Principles
+- **Single Responsibility**: Each class has one reason to change
+- **Open/Closed**: Open for extension, closed for modification
+- **Liskov Substitution**: Subtypes are substitutable for their base types
+- **Interface Segregation**: Clients depend only on methods they use
+- **Dependency Inversion**: Depend on abstractions, not concretions
+
+### Clean Code Practices
+- **DRY** (Don't Repeat Yourself): No code duplication
+- **KISS** (Keep It Simple, Stupid): Simple, straightforward solutions
+- **YAGNI** (You Aren't Gonna Need It): Only implement what's needed
+
+### Code Quality
+- Comprehensive documentation (JavaDoc/JSDoc)
+- Meaningful names for all classes, methods, and variables
+- Small, focused functions (< 30 lines)
+- Proper error handling throughout
+- Extensive validation
+- Logging at appropriate levels
+- Type safety everywhere
+
+See [ARCHITECTURE.md](./ARCHITECTURE.md) for detailed information.
+

+- **Framework**: Spring Boot 3.4.1
+- **Language**: Java 21
+- **Security**: Spring Security 6.3.4
