I will fix next js supabase bugs, auth, rls and database issues
Umer Mushtaq
About this gig
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.

FAQ
What types of Next.js issues can you fix?
I can troubleshoot Next.js application errors, API integration problems, authentication flows, application logic, frontend/backend communication, database-related issues, performance problems and deployment errors.
Can you fix Supabase authentication issues?
Yes. I can troubleshoot Supabase authentication problems involving login, signup, sessions and related authentication flows.
Can you fix Supabase RLS policy issues?
Yes. RLS debugging is included in the Standard and Premium packages. I can investigate policies that incorrectly block or allow database operations and fix the relevant application/database logic.
Can you fix Supabase database and query issues?
Yes. I can diagnose database queries, data-access problems, application/database integration and related PostgreSQL/Supabase issues.
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.
Can you fix Vercel or deployment problems?
Yes. Deployment debugging is available with the Premium package or can be added separately depending on the issue.
Can you work on an existing codebase?
Yes. This gig is specifically designed for diagnosing and fixing problems in existing Next.js and Supabase applications.
What access do you need?
Depending on the problem, I may need access to the relevant source code/repository, Supabase project configuration, logs, error messages and deployment environment. Please never send passwords or sensitive credentials directly in chat.
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.
Should I contact you before ordering?
Yes, especially if you're unsure about the cause of the issue. Send me the error and a short description, and we can determine the appropriate scope before you order.
