Code Cupid would be a great tool if users could register for an account and use it to keep track of their contributions or open source projects they're working on, as well as allowing multiple users to pair on projects.

This milestone involves several complex tasks, including:

• adding authentication to the backend
• adding a user data table or tables that keep track of a user's ID and the repositories they've contributed or are currently working on and details such as number of commits contributed, etc.
• adding a sign-up/sign-in page to the frontend
• adding a user profile page to the frontend
• allowing users to add each other to pair on projects
