Jiatao Geng modernized the navigation user interface for the UWOrbital/OBC-firmware repository, focusing on unifying the navigation experience across the MCC and ARO interfaces. He migrated the MCC navigation system to use React Router, replacing legacy links with a standardized, route-based approach. The redesign included updating the navbar to feature the UW Orbital logo on a black background, ensuring visual consistency and improved usability. Working primarily with React, TypeScript, and CSS, Jiatao established a consistent cross-application user experience that streamlines future feature development. The scope of work was focused but delivered a foundational improvement to the application's frontend architecture.
