John Bepo
About this gig
Most Supabase and Firebase backends get rushed especially ones wired up fast through Lovable, Bolt, Replit, or Cursor.
What usually ships: open database rules, no Row Level Security, exposed API keys, or auth that "works" but isn't actually locked down. That's a data leak waiting to happen.
I can build, configure, secure, troubleshoot and integrate your backend using Supabase, Firebase , MongoDB and PostgreSQL.
WHAT I CAN BUILD
- Supabase & Firebase backend
- PostgreSQL /Firestore /MongoDB databases
- Email, Google/OAuth, JWT & MFA authentication
- REST APIs & webhooks
- Row Level Security (RLS) & RBAC
- Database schema & relationships
- Realtime database features
- Edge Functions & Cloud Functions
- Firebase FCM push notifications
- Android, iOS & Capacitor notifications
- File/storage configuration
- Frontend/backend integration
- Security configuration & backend audit
- Database migration & optimization
- AI agent, chatbot & API integration
- Production deployment
- Backend bug fixing & troubleshooting
I can work with React, Next.js, React Native, Flutter, FlutterFlow, Capacitor, Lovable, Base44, Replit, Bolt.new and Claude Code projects.
Send your current setup, let's build it correctly.
