An intelligent restaurant ordering system integrating AI-assisted decision making, Strategy Pattern, and modular architecture for flexible order processing and discount management.

Highlights

• AI-assisted discount recommendation using Gemini API to determine the optimal promotion strategy.
• Reflection-based AI Agent for dynamic function discovery and tool invocation.
• Implemented Strategy Pattern to encapsulate multiple discount rules and improve extensibility.
• Event-driven architecture separating order processing, discount calculation, and UI rendering.
• Externalized business rules using JSON configuration, allowing menus and promotional campaigns to be updated without modifying application code.

A lightweight Dependency Injection Container implemented from scratch using Reflection and Constructor Injection.

Highlights

• Built a lightweight Dependency Injection Container from scratch using Reflection and Constructor Injection for automatic dependency injection.
• Implemented Recursive Dependency Resolution to recursively construct complete dependency graphs at runtime.
• Implemented Attribute-based Auto Registration to discover and register services through Reflection with minimal configuration.
• Supports IEnumerable<T> Resolution for resolving multiple implementations of the same service interface.
• Provides PresenterFactory and ComponentFactory to integrate the MVP architecture, improving modularity and reducing coupling between the UI and business logic.
