• Change the existing Promise<object> to a well-defined interface.
• Ensure that API routes are both self-explanatory and aligned with their respective functionalities.
• Refactor responses by populating only the necessary fields in the response.
• Implement RoleGuards for role-specific authentication to APIs.
• End-to-end testing.
• Check API status and status codes for consistency.
• Error logs should be there when necessary.
• ESLint rules should not be disabled unless necessary.
• Validation on Payload.
