They implemented login and signup APIs with session management, integrated wishlist functionality, and refactored authentication flows for maintainability. Using TypeScript, React, and Tailwind CSS, they standardized component styling, improved state management, and applied consistent code formatting with Prettier. Their work included updating Storybook documentation and optimizing build configurations. Additionally, they enhanced the gathering detail modal in CodeitFESI4-Team1/CodeitFESI4-Team1, restructuring UI elements to improve information hierarchy and user interaction, demonstrating full stack development skills.
