Technical implementation details
Technical implementation details
The Angular application was structured around feature modules with clear separation:
• Core Module: Authentication, guards, interceptors, and global services
• Shared Module: Common components, directives, and pipes
• Feature Modules: Functionality-specific components for shipment, orders, and address validation
The RESTful API was designed with these principles:
• Resource-oriented endpoints
• Standardized response formats
• Proper HTTP status code usage
• Versioning support for backward compatibility

The address validation process implemented a multi-step pipeline:
• Batch upload of addresses from client
• Syntactic validation of address format
• Geographic validation against postal reference data
• Delivery point assignment
• Route integration and optimization
The route generation algorithm considered:
• Optimal delivery sequence
• Logistics network topology
• Resource allocation efficiency
• Time-window constraints
