PROFILE

Teo Zhi Xian

Over a two-month period, this developer enhanced the LifeSG/web-frontend-engine by implementing session-based upload tracking for ImageUpload and FileUpload components. Using React and TypeScript, they introduced a sessionId prop to enable session-scoped validation and tracking, updated type definitions for backward compatibility, and ensured sessionId inclusion in upload payloads for improved data integrity and traceability. Additionally, they contributed to the LifeSG/react-design-system by fixing a popover interaction bug on mobile devices, refining handleBlur behavior to maintain popover visibility during touch interactions. Their work focused on component reliability, user experience, and robust frontend development practices across both repositories.
