During July 2025, Sangmi worked on the adobe/react-spectrum repository, focusing on aligning Storybook Toaster component naming conventions to clarify experimental status and reduce import errors. She updated Storybook stories to reference ToastContainer and ToastQueue with an UNSTABLE_ prefix, ensuring that consumers could easily identify experimental components and import them accurately. This change addressed potential confusion in the development workflow and improved the clarity of component usage within Storybook. Sangmi utilized her front-end development skills with React, Storybook, JavaScript, and TypeScript to implement this targeted feature, demonstrating attention to detail in maintaining consistency and reliability in component documentation.
