Over a two-month period, contributed to the next-engineer/next-java-exercise repository by delivering core business features such as library and student management, account and employee systems, and a customer loyalty module. Applied object-oriented programming principles in Java, leveraging design patterns like Builder, Adapter, and Strategy to create modular, maintainable code. Refactored project structure and removed legacy notification and student processing code to reduce technical debt and improve scalability. Implemented a strategy-based calculator with robust error handling for arithmetic operations. Focused on code organization, dependency injection, and interface design, resulting in cleaner, more extensible utilities and safer, future-ready core functionality.
