About this gig

Struggling to connect your frontend to Supabase API, authentication, or database?


I help developers and founders integrate Supabase smoothly so your React or Nextjs app works exactly as expected.


Many apps built on modern stacks fail at the integration stage API calls break, authentication doesnt persist, or database queries return errors. This slows development and affects user experience.


I will connect your frontend to Supabase backend, ensuring API integration, authentication flow, and database communication are properly configured and working reliably.



What you'll get:

  • Connect frontend to Supabase API endpoints
  • Implement authentication (login, signup, session handling)
  • Integrate database queries and real-time data
  • Fix broken API calls or connection issues
  • Clean, tested integration ready for production


I focus on stable, maintainable integrations that support real SaaS and MVP builds not quick hacks.


If your app isnt fully connected or behaving inconsistently, Ill help you get it working properly and ready to scale.



Message me before ordering with your setup and Ill guide you on the best approach.
