About this gig

Having issues with Supabase authentication? I can help.

I will troubleshoot and fix authentication problems in your web application using Supabase, whether you are using Next.js, React, Astro, or another JavaScript framework.


I can help with:


  • Email and password authentication
  • Magic links and OTP
  • Google OAuth
  • Login and signup issues
  • Session and authentication state problems
  • Redirect and callback issues
  • Supabase configuration
  • Environment variables
  • Row Level Security related access issues
  • Production authentication errors
  • OAuth configuration and callback URLs

My process:

  1. Identify the root cause of the issue
  2. Implement the necessary fix
  3. Test the authentication flow
  4. Make sure everything works correctly in your environment


I do not just provide generic code. I will investigate the actual problem in your project and work on a proper solution.


Please contact me before ordering and briefly describe the issue you are experiencing. I will let you know which package is the best fit.
