- Architected a full-featured desktop calendar application in Java using the MVC pattern, cleanly separating UI (Swing), business logic, and data layers to maximize maintainability and extensibility.
- Applied an Event-Bus pattern for loosely coupled, asynchronous communication between the View and Controller, eliminat- ing direct dependencies and making components independently testable.
- Leveraged four Gang-of-Four design patterns — Command, Builder, Adapter, and Factory — to produce a modular, exten- sible codebase; each feature addition required zero changes to existing classes, demonstrating the Open/Closed Principle in practice.
- Practiced strict Test-Driven Development with JUnit, writing tests before implementation across all core modules — reducing debugging time and cutting overall development time by 68%.
- Produced UML Object and Class diagrams to formalize system design upfront, serving as shared reference artifacts that facilitated cross-team design reviews and onboarding.
