The frontend uses Bootstrap 5 for responsive design, providing modern UI components, grid system, and utility classes. Custom CSS extends Bootstrap with procurement-specific styling including gradient headers, card layouts, and interactive elements. The static file management uses Django's static files framework with WhiteNoise middleware for efficient static asset serving in production. The authentication system uses Django's built-in user authentication with session-based authentication, providing secure login, logout, and user management. Custom template tags enable role-based UI rendering, distinguishing between authority users and supplier users. The database layer uses PostgreSQL with proper connection pooling, parameterized queries for SQL injection prevention, and comprehensive indexing for query optimization. The platform implements proper middleware including security middleware, session middleware, CSRF protection, authentication middleware, and WhiteNoise for static files. The admin interface uses Django's built-in admin with custom styling, providing comprehensive administrative capabilities with custom admin classes, inline editing, and advanced filtering. The platform is deployed using Railway with PostgreSQL database service, providing automated database provisioning, connection string management, and scaling capabilities. Railway provides automated CI/CD with GitHub integration, enabling automatic deployments on code pushes with health checks and restart policies. Environment configuration uses hardcoded production settings for simplified deployment, removing the need for environment variable management. The backend uses Gunicorn as the WSGI server for production deployment, providing efficient request handling and process management. The architecture supports horizontal scaling through stateless application design and implements proper error handling, logging, and monitoring capabilities. Security is implemented through multiple layers including CSRF protection, secure session management, proper authentication flows, and input validation throughout the application.
