Worked on the Automattic/wp-calypso repository to enhance the Reader sidebar by improving how followed sites are identified when they lack a title. Developed a feature that displays the custom domain instead of the default WordPress subdomain, addressing user experience and clarity. Implemented the getReaderSidebarSiteName() helper in TypeScript, ensuring consistent display logic through normalization and handling of trailing-slash edge cases. Added comprehensive unit tests to validate the new behavior and maintain code quality. Utilized React and front end development skills to deliver maintainable utilities, ultimately reducing support friction and making site identification more intuitive for users in the Reader interface.
