Developed and delivered a GPA Calculator Application for the Michaelkelly71/Acity_CPP_Project repository, focusing on educational tooling. The application provided a graphical user interface using Java Swing, allowing users to input student information, course details, and grades, then calculate GPA and save results to a file. Emphasizing clean design and reusability, the implementation leveraged Java for both GUI development and file I/O operations, ensuring robust input validation and a clear user workflow. No major defects were reported during the development period, and the feature was shipped as a modular component to support future enhancements and integration within the project’s ecosystem.
