FAQ
Should I choose Firebase or Supabase?
Firebase is great for realtime apps, push notifications and quick setup. Supabase gives you a Postgres SQL database with row-level security. I will recommend the best fit for your data and budget.
Does this work with Expo apps?
Yes. I work with both Expo and bare React Native projects, including Expo EAS builds.
Who owns the backend project?
You do. The Firebase or Supabase project is created under your account and you add me as a collaborator. You also get the full source code.
Can you connect my existing backend or API?
Yes. I can integrate your existing REST API, Express server, Firebase or Supabase project into your app.
How do you keep user data secure?
Firebase security rules or Supabase row-level security, secure token storage, no secret keys inside the app, and server-side checks for sensitive actions.
Will the backend be expensive to run?
Firebase and Supabase both have free tiers. I design the database to keep reads and costs low, and explain what to expect as your app grows.
Can you build a new app from scratch?
This gig adds a backend to an existing React Native app. For a complete new app, check my React Native mobile app development gig on my profile.
What does free support cover?
For 7 days after delivery I fix any bugs in the backend features I delivered. New features are quoted separately.
