I will fix next js supabase bugs, auth, rls and database issues
Umer Mushtaq
Sobre este Serviço
Having trouble with your Next.js or Supabase application?
I will diagnose and fix bugs in your existing Next.js + Supabase app, focusing on the root cause instead of applying temporary workarounds.
I can help with:
- Next.js bugs and errors
- Supabase Auth, login, signup & session issues
- Row Level Security (RLS) policies
- PostgreSQL & database query issues
- API and frontend/backend integration
- Data access & permission problems
- Application logic bugs
- Performance issues
- Vercel & deployment errors
I have hands-on experience building and debugging production applications using Next.js, React, TypeScript, Node.js, Supabase and PostgreSQL.
Whether you're facing a broken auth flow, RLS blocking your queries, database errors, API issues, or a difficult bug you can't trace, I can help identify and resolve it.
Please message me before ordering with the issue, error message/screenshots, and expected behavior so I can confirm the right package and solution for you.

Which package should I choose?
Choose Basic for one small, clearly defined issue. Standard is suitable for up to 3 related issues involving areas such as auth, RLS, APIs or database logic. Premium is intended for deeper debugging involving up to 5 related issues, performance, architecture or deployment.

What counts as one issue?
One issue is one clearly defined bug or problem with a specific expected behavior. Multiple unrelated errors or features may count as separate issues.
