Nathan Tran focused on backend integration and frontend development for the SCE-Development/Clark repository, addressing a critical authentication issue during January 2025. He resolved a bug that affected session persistence by ensuring the JWT token was correctly extracted and stored in localStorage, which allowed user sessions to persist across reloads. Nathan also updated the User model to include a default background color, improving the user experience. Working primarily with JavaScript, he enhanced the security and reliability of the authentication flow. While the work was limited to a single bug fix, it demonstrated careful attention to detail and a solid technical approach.
