User Profiles Setup Firebase Authentication and

Project Overview: We need a developer to implement a secure user authentication flow and connect it to a database to store user profile information. Expected Output: - Secure user signup, login, and logout functionality using email/password. - Upon successful signup, a corresponding user document must be created in the database to store custom profile data (e.g., display name, profile picture URL, and registration date). - Protected client-side routes that redirect unauthenticated users back to the login page. Required Skills: - ReactJS - Firebase (Auth & Firestore) or Supabase - Experience managing state for authenticated users Important Details: The login and registration UI forms are already built and styled. This task is strictly focused on wiring up the authentication logic, database writes, and protecting the routes.
