Worked on the aidenybai/react-scan repository to address UI stability and maintainability by resolving a styling issue affecting scrollbar appearance across the application. Applied precise CSS scoping techniques to limit scrollbar styles specifically to the '#react-scan-toolbar' element, preventing unintended global overrides and reducing the risk of cross-component conflicts. This targeted bug fix improved UI consistency and established clearer boundaries for future CSS maintenance. Leveraged skills in CSS, TypeScript, and front end development while managing changes through Git and aligning with tracked issues. The work demonstrated disciplined change management and a focus on maintainable, conflict-free user interface design.
