During December 2024, Yaoyao worked on the CurtainWallWeb-Frontend repository, focusing on restoring and strengthening user authentication. By updating the proxy configuration and aligning the agent’s target URL with the new backend endpoint, Yaoyao ensured that login requests were correctly routed and authenticated. The work involved uncommenting the actual API call for login and validating the end-to-end authentication flow, which reduced login failures and improved onboarding reliability. Using JavaScript, TypeScript, and Nuxt.js, Yaoyao’s efforts addressed a critical bug rather than adding new features, demonstrating depth in API integration and frontend development to resolve a high-impact access issue.
