Worked on the CurtainWallWeb-Frontend repository to restore and harden user authentication, focusing on resolving a critical login issue that impacted user access. Addressed the problem by updating the proxy configuration, uncommenting the actual API call for login, and aligning the agent configuration with the new backend endpoint. Validated the end-to-end authentication flow to ensure login requests reached the correct service, which reduced failures and improved onboarding reliability. Utilized JavaScript and TypeScript within a Nuxt.js frontend, applying API integration skills to deliver a robust solution. The work emphasized reliability and maintainability in the authentication process for end users.
