Andy Liu developed a suite of educational and utility-focused features for the ia2407-114/113-2-junior-college-C-plus-plus-program repository, emphasizing modular C++ and PHP solutions. He implemented object-oriented C++ programs for student records, geometric calculations, and data validation, using class inheritance, input/output handling, and exception management to ensure maintainability and data integrity. Andy also delivered a PHP-based MySQL database abstraction layer, centralizing connection management and query execution to streamline backend data access. His work included front-end enhancements with HTML and CSS, as well as repository refactoring for scalability. The engineering approach demonstrated depth in both backend and application-level problem solving.
