## Code Review and Next Steps

Based on our previous session, here's a summary of what we've accomplished and what's next:

### Completed Tasks
- Implemented user authentication using OAuth 2.0
- Created a database schema for user profiles
- Set up basic CRUD operations for the profile data

### Code Snippets
```javascript
// OAuth 2.0 Authentication Middleware
app.use('/api', authMiddleware);

// User Profile Schema
const userSchema = new mongoose.Schema({
  googleId: String,
  displayName: String,
  email: String,
  profilePicture: String
});
```

### Next Steps
1. **Implement profile picture upload**: We need to create an endpoint for handling profile picture uploads.
2. **Add profile validation**: We should validate the user's profile data before saving it to the database.
3. **Create profile update endpoint**: We need an endpoint to update the user's profile information.

Would you like me to help you with any of these tasks or review the code we've already written?
