About this gig
Need help with your Supabase or Firebase backend?
I can build, fix, secure, and optimize your backend for web apps, SaaS products, MVPs, and AI-generated applications.
I can help with:
- Supabase or Firebase setup
- Database design and configuration
- Authentication and user accounts
- Login, signup, Google OAuth, and social auth
- Supabase Row Level Security (RLS)
- Firestore security rules
- API integration
- Storage and file uploads
- Realtime functionality
- Edge Functions / Cloud Functions
- Database migrations
- Bug fixing and debugging
- Frontend-to-backend connection issues
- Performance and security improvements
- Lovable, Bolt, Replit, Cursor, and AI-built app fixes
If your app was generated using AI and the backend is not working correctly, I can inspect the project and fix the underlying Supabase or Firebase issues.
Please message me before ordering if your project is complex so I can review the requirements.

Hi, I'm Samir — a full-stack developer from Morocco with 7+ years of experience building web applications from the ground up.
I work with JavaScript, Python, PHP, React, Node.js, and Laravel, covering everything from database design and APIs to polished frontend interfaces.
I also build AI-powered products, including OpenAI integrations, chatbots, automation, and intelligent web applications.
My focus is clean, scalable, production-ready code — not quick prototypes that fall apart when they grow.
Need solid engineering with modern AI capabilities? Let's build it.

FAQ
Do you work with both Supabase and Firebase?
Yes. I can work with Supabase, PostgreSQL, Firebase Authentication, Firestore, Storage, Functions, and related backend services.
Can you fix an app created with Lovable, Bolt, Replit, or Cursor?
Yes. I can troubleshoot AI-generated apps and fix problems with authentication, databases, permissions, APIs, and backend configuration.
Can you fix Supabase RLS errors?
Yes. I can create and debug Row Level Security policies and make sure users can only access the data they are supposed to access.
Can you migrate Firebase to Supabase?
Yes. I can help migrate databases, authentication, storage, and application logic depending on the project.
Do you build the frontend too?
I can fix frontend/backend integration issues. For a complete frontend build, contact me first so the scope can be discussed.
Do I need to give you my passwords?
No. Where possible, use project invitations, temporary access, environment variables, or other limited-access methods rather than sharing account passwords.
