Worked on the DpTuApp repository over four months, delivering seven features and resolving one bug with a focus on backend and UI development using Java and Java Swing. Enhanced the StudentModel to support tutoring session tracking, improved data loading robustness, and established reliable data paths between backend models and the UI. Introduced localization and dynamic messaging to prepare the application for multilingual support, refactored core modules for maintainability, and implemented algorithmic features such as matrix chain multiplication with backtracking. Addressed event listener duplication to improve reliability, demonstrating a methodical approach to code quality, documentation, and integration of software design patterns.
December 2025: Delivered robustness and capability enhancements for matrix problems in DpTuApp. Implemented backtracking integration for MatrixChainProblem (state management and parenthesization tracking) and integrated into the main execution flow; introduced Matrix dimensions input UI with add/remove and validation; fixed duplicate event listener registration in Problem class with null-check to prevent multiple listeners. These changes improve algorithm capability, reliability, user experience, and maintainability, aligning with DPTU-83, DPTU-101, and DPTU-103/104.
