Using React and TypeScript, Agastelum Flores built and refined Storybook testing scaffolding to validate the fix, optimizing story render logic and maintainability. They also added targeted unit tests and addressed linting issues, supporting a smoother release process. This work enhanced card input UX reliability and established a more robust, QA-ready validation workflow for card components.
