Over a two-month period, contributed to both the supminn/momentum-design and webex repositories by building accessible, user-focused features. Developed a versatile dialog component for momentum-design, implementing accessibility options, focus trapping, and flexible footer management using Lit, CSS, and Web Components to support robust modal workflows. In the webex-js-sdk and webex/widgets repositories, enhanced dialing accuracy and onboarding UX by introducing international dial-number validation and improving station login flows with React and TypeScript. These updates established reusable validation patterns and improved global usability, demonstrating a focus on accessibility, component design, and seamless user experiences across multiple products and platforms.
