Esther D
About this gig
Is your Firebase project becoming difficult to maintain, expensive to scale, or full of migration and backend issues?
I will migrate your Firebase application to Supabase and fix the backend problems that may appear during or after migration.
I can migrate and configure Firestore, Firebase Authentication, Firebase Storage, backend logic, APIs, and database structures while converting your data to a clean Supabase PostgreSQL architecture.
My services include:
- Firebase to Supabase migration
- Firestore to PostgreSQL migration
- Firebase Auth to Supabase Auth
- Firebase Storage migration
- Database schema conversion
- Authentication bug fixing
- Backend bug fixing
- Supabase RLS policies
- API and connection fixes
- Database query troubleshooting
- Data validation and testing
- Post-migration debugging
I can also troubleshoot projects built with Next.js, React, Node.js, TypeScript, Lovable, Replit, Bolt, and other modern development platforms.
My goal is not simply to move your data. I will help ensure your application continues working correctly after the migration with a secure, maintainable, and scalable Supabase backend.
Please message me before ordering.

FAQ
Can you migrate my entire Firebase project to Supabase?
Yes. I can migrate Firestore data, Firebase Authentication, Storage, database structure and relevant backend logic to Supabase. The exact scope depends on your project architecture, data volume and Firebase services currently being used.
Can you migrate Firestore to Supabase PostgreSQL?
Yes. I can convert your Firestore structure into a properly designed PostgreSQL schema, transform the data where necessary, migrate records, and verify that the resulting Supabase database works correctly with your application.
Can you migrate Firebase Authentication to Supabase Auth?
Yes. I can configure Supabase Auth and help migrate your existing authentication system. Email/password and supported OAuth providers can be handled depending on your current Firebase configuration and project requirements.
Can you fix bugs after migrating Firebase to Supabase?
Yes. I can troubleshoot broken queries, authentication issues, API errors, database connection problems, RLS errors, missing data and other backend problems introduced during the migration.
Will my Firebase data be preserved?
I will carefully structure and validate the migration to preserve your important data. Before starting, I review your Firebase database, authentication requirements and data relationships so the migration approach matches your project.
Can you migrate Firebase Storage to Supabase Storage?
Yes. I can help move files and configure Supabase Storage, including buckets and access policies. Storage migrations depend on file volume, existing permissions and how your application currently references uploaded files.
Can you set up RLS after migration?
Yes. I can create Row Level Security policies for your Supabase tables based on your application's user roles and data-access requirements, helping prevent unauthorized users from accessing protected database records.
Can you migrate a Lovable or AI-generated app?
Yes. If your Lovable, Replit, Bolt or similar application uses Firebase, I can migrate the backend to Supabase and troubleshoot broken authentication, database queries, environment variables and API connections.
Do you test the application after migration?
Yes. I test the migrated functionality and check authentication, database operations, API requests and relevant backend features. This helps identify migration issues before the project is considered complete.
Should I migrate from Firebase to Supabase?
It depends on your application. If you want PostgreSQL, SQL querying, RLS and a more relational database architecture, Supabase may be a strong option. Send me your current Firebase setup and I can assess the migration requirements.
