Looks Like This Service Is On Hold
I will secure supabase or firebase backend and fix misconfigurations
Abdul Moiz
About this gig
Is your app's database wide open to the public?
AI coding tools (like Cursor, Base44, Bolt.new, Lovable, v0 etc) and no-code builders are amazing for building apps fast, but they notoriously fail at one critical thing: "Backend Security". A single misconfiguration can ruin your app. Let me lock it down.
What I Will Do For You:
Supabase Security: Implement robust Row Level Security (RLS) policies using PostgreSQL so users can only access their own data.
Firebase Security: Write optimized Firestore or Realtime Database Rules to prevent unauthorized read/write access.
API Token Protection: Identify and secure exposed API keys (like the dangerous Supabase Service Role key) to prevent complete project takeovers, and draining your quota causing massive billing spikes.
Vulnerability Audit: Scan your entire current setup for misconfigurations, data leaks, and weak permission models.
Why Choose Me?
I specialize in fixing and securing backends for modern web and mobile apps. I don't just write generic rules. I analyze your specific app logic to make sure the security rules do not break your app's functionality.

FAQ
Do you need access to my Supabase or Firebase account?
Yes. I will need you to invite my email address to your Supabase or Firebase project as a developer/collaborator so I can write and test the rules.
I built my app with an AI tool (Bolt/Lovable/Cursor). Can you secure it?
Absolutely! AI tools are fantastic for the frontend but often leave backends completely exposed. I specialize in stepping in, reading the AI's structure, and locking down the database securely.
Will adding these security rules break my app?
If done incorrectly by a beginner, yes. But I carefully review your app's read/write requests and thoroughly test the RLS policies and Firebase rules to ensure your app functions perfectly while keeping bad actors out.
