During May 2025, Mazab Abubakar contributed to the cse110-sp25-group19 repository by establishing the foundational structure for a game development project. He created initial stub files for game logic and utility functions in JavaScript, incorporating JSDoc comments to support future extensibility and maintainability. Mazab also updated the main HTML file to integrate these new modules, ensuring a modular and scalable front end. Additionally, he improved code readability by standardizing spacing and formatting in utility scripts, focusing on consistency without altering functionality. His work demonstrated solid front end development skills and attention to code quality, though it remained foundational in scope.
