Worked on microsoft/fluentui-blazor to deliver two targeted front end enhancements over a two-month period. Developed touch-driven split panel resizing, enabling users to adjust panel sizes on touch devices by implementing touchmove and touchend event handling in TypeScript. This improved mobile usability and broadened device compatibility for the component library. Additionally, enhanced UI theming flexibility by adding accent-color support to reboot.css, allowing for streamlined theme customization across Blazor applications. Focused on minimal, high-impact changes with clear commit practices, leveraging skills in TypeScript, CSS, and UI/UX design to address specific usability and design-system alignment needs without introducing bug fixes.
