Worked on the Telefonica/mistica-web repository to enhance accessibility and embedding support by addressing focus management issues in the Sheet component. Developed a custom React hook using TypeScript and JavaScript to detect when the component is running inside an iframe, enabling conditional disabling of the FocusTrap feature in nested environments. This solution improved user experience for embedded deployments by preventing focus conflicts that can arise within iframes. The update aligned with broader goals to support iframe integrations while maintaining accessibility standards. The work demonstrated a focused approach to front-end development, emphasizing practical problem-solving and careful attention to user interaction in complex contexts.
