Developed an interactive user interface feature for the MIAGE-INF1-2024-2025 repository, introducing two selectable squares whose background colors change randomly, with a toggle to enable or disable the animation. The implementation focused on robust state management and responsive client-side behavior, enhancing user engagement through direct UI controls. Built using HTML and JavaScript, the feature was delivered as a single, well-documented commit, ensuring clarity and maintainability for future extensions. No bugs were reported during the development period, reflecting careful attention to code quality. The work demonstrates foundational front end development skills and a methodical approach to interactive component design and delivery.
