Worked on accessibility optimization for the Cloudscape Alert component in the cloudscape-design/components repository, focusing on improving ARIA semantics for better screen-reader navigation. Addressed an accessibility issue by adding a role of "group" to the alert focus wrapper, ensuring that assistive technologies can more accurately interpret alert structures. Introduced a regression test to verify that the element referenced by the alert’s focus ref maintains the correct group role, reducing accessibility risk while preserving existing behavior. Utilized React, JavaScript, and TypeScript to implement and test these changes, supporting inclusive design goals and enhancing the overall accessibility of front-end components.
