Security Features

• Input validation and sanitization
• SQL injection prevention (prepared statements)
• CORS policy implementation
• Structured error handling (no sensitive data exposure)
• Request logging for audit trails

Scalability Considerations

• Database: SQLite for development, PostgreSQL-ready for production
• Caching: Redis integration ready
• Load Balancing: Stateless API design
• Microservices: Modular architecture for service separation
