I will set up a secure firebase or supabase backend for your app

Your app needs a backend that is secure, scalable and cheap to run. I set up Firebase or Supabase properly so you never ship an open database.

I work with Firebase and Google Cloud daily as a backend engineer (Dart SDKs, Cloud Functions, Workload Identity Federation) and use Supabase Postgres with Row Level Security on multi-department production apps.

What you get:

• Firebase Auth or Supabase Auth: email, phone OTP, Google or Apple sign-in, custom claims and roles
• Firestore or Postgres schema designed for your queries, with tested security rules or RLS policies
• Cloud Functions or Edge Functions: triggers, webhooks (Stripe, M-PESA), scheduled jobs, callable APIs
• Storage buckets with rules, FCM push notifications, analytics and crash reporting wired in
• Emulator setup, separate dev and prod environments, and a handover document

Also available: migrating from Firebase to Supabase (or the reverse), tightening existing rules, and fixing permission-denied errors.

Message me with your app details so I can confirm scope.
