• Request validation
• Rate limiting and circuit breaking
• File upload handling
• QR code generation for route sharing
• Monitoring and metrics collection

• Java 21
• Spring Boot 3.4.4
• Spring Security with JWT
• OAuth2 for social login
• MongoDB for configuration storage
• Elasticsearch for search capabilities
• Kafka for event messaging
• Cloudinary for image uploads
