Hasan Onur Can Sarihan focused on front end development for the Civilian Cargo Terminals across tgstation/tgstation, NovaSector/NovaSector, and BurgerLUA/Bubberstation, addressing persistent UI layout issues. He resolved initial render sizing bugs by applying the grow property to Flex.Item components, ensuring terminals adjusted correctly on first render and eliminating visual inconsistencies. Working with React, JSX, and JavaScript, Hasan standardized UI patterns across multiple repositories, coordinating fixes that improved user experience and interface stability. His work demonstrated a disciplined approach to cross-repo collaboration, emphasizing maintainable code and consistent behavior, and contributed to a more reliable and predictable frontend architecture.
