Over two months, contributed to the 100-hours-a-week/5-team-oishikunare-gangazido-fe repository by delivering user authentication and profile management features focused on robust error handling and improved user experience. Enhanced login flows by consolidating error messages and introducing explicit feedback for invalid email formats, refactoring the logic for maintainability and localization readiness. Unified user profile image delivery through CloudFront CDN integration, streamlined image upload and deletion, and strengthened resilience to missing S3 images. Improved registration and profile validation with clearer user-facing messages and API-level 429 error handling. Worked primarily with JavaScript, React, and CSS, emphasizing frontend development and API integration best practices.
