During April 2025, Oktavia Simatupang enhanced the DairyTrack platform by developing a responsive Contact Us page within the T0MM11Y/DevelopmentOf-DairyTrack-Platform repository. She focused on improving user experience through refined layout organization, enhanced map presentation, and better form usability, ensuring accessibility and consistency across devices. Using React, JavaScript, and CSS, Oktavia addressed UI inconsistencies by polishing the embedded Google Maps iframe styling and aligning footer text for a cleaner interface. While no critical bugs were reported, her work emphasized cross-device usability and adherence to UX best practices, demonstrating a solid grasp of front-end development fundamentals within a focused project scope.
