RepSeeker – Gmail-Integrated Job Application Tracker

Contributed to the development and debugging of RepSeeker, a web-based platform that helps users track and manage job applications by integrating with their Gmail accounts. The platform uses the Google OAuth2 flow to securely access user email data, enabling automated tracking of application-related emails. I played a key role in fixing the authentication and token exchange logic between the frontend and Firebase Cloud Functions to ensure a reliable and seamless login experience.
