Worked on the baidu/amis repository to enhance front-end component reliability and performance using React, JavaScript, and TypeScript. Delivered targeted improvements by fixing a nested collapsible UI state issue, ensuring that collapsing a child element no longer triggers unintended parent state changes. Optimized FieldSet rendering by removing unnecessary data and store props, which reduced redundant re-renders and improved interface responsiveness. Addressed a data context bug in Table2 expandable rows, allowing components to access complete row data for more robust data handling. These changes collectively stabilized UI interactions and strengthened data contracts, resulting in a more predictable and efficient user experience.
