FAQ
Which backend is better: Firebase or Appwrite?
It depends on your project. Firebase is excellent for rapid scaling and Google ecosystem integration, while Appwrite offers great self-hosting flexibility and privacy. I can help you choose the best one for your specific needs.
Why should I hire a developer with research experience?
As a published researcher with 3 papers in international conferences, I apply a higher level of logic and debugging to your project, ensuring fewer crashes and better performance.
Can you integrate third-party APIs with the backend?
Yes, I can connect your backend to external services like Stripe for payments, Twilio for SMS, or Google Maps.
Can you migrate my existing app from Firebase to Appwrite (or vice versa)?
Yes, I can handle data migration and reconfigure your Flutter app to work with a new backend provider while ensuring no data loss.
How do you ensure my user data is secure?
I implement strict Security Rules for Firestore or Appwrite. This ensures that users can only access their own data and prevents unauthorized API calls.
Do you handle "Push Notifications" setup?
Yes, I configure Firebase Cloud Messaging (FCM) so you can send real-time alerts to both Android and iOS users.
What state management do you use for backend-heavy apps?
I typically use BLoC or Provider. This ensures that your app’s UI stays in sync with the database without performance lags.
Can you build an Admin Panel to manage my database?
Yes, I can develop a Flutter dashboard that allows you to manage users, products, or content without touching the code.
Will you provide the backend configuration documentation?
Yes, I provide a "Handover Document" explaining how your database is structured and how to manage your backend console.
Do you offer maintenance after the app is live?
Yes, I provide a support period to ensure your database and APIs are running smoothly after the launch.
