Lorena Gonzalez enhanced accessibility in the factorialco/factorial-one repository by updating the CardLink component to render as a native button when no href is provided. This adjustment improves both usability and compliance with accessibility standards, ensuring users experience consistent interactions regardless of context. Lorena implemented comprehensive tests to validate CardLink’s behavior in scenarios with and without an href, reducing the risk of regressions and supporting stable releases. The work focused on front end development using React, JavaScript, and TypeScript, demonstrating careful attention to maintainability and user experience through targeted, high-value changes delivered within a single feature release cycle.
