Worked on the narmi/design_system repository to deliver targeted improvements to customer-facing UI components, focusing on both feature development and bug resolution. Enhanced the Combobox component by implementing an auto-close behavior on selection and ensuring reliable menu toggling, which improved user interaction and visual consistency. Addressed a visual alignment issue in menu buttons by resetting specific CSS margins, restoring proper layout and reducing visual regressions. Utilized JavaScript and SCSS to refine component behavior and appearance, applying front-end development and UI/UX skills to increase design-system reliability. The work emphasized measurable business value through stability fixes and consistent, user-friendly interface enhancements.
