I will fix claude code supabase setup backend errors v0 website design rls auth mcp bug
Joshua
About this gig
Is your Claude Code or Supabase backend broken? RLS errors, auth failures, MCP issues or a v0 website that will not deploy can stop your project cold.
I fix these fast so you stop burning time and tokens on retry loops that go nowhere.
I specialize in diagnosing Claude Code and Supabase integration bugs: Row Level Security policy violations, JWT and auth misconfigurations, MCP tools missing from Code sessions, failed edge function deploys, broken migrations and v0 frontend errors that break on launch.
Whether your app was vibe coded start to finish or a mixed stack, I read the error logs and fix the real root cause, not just the symptoms
Send me your error message, repo access or screenshots. I diagnose the exact failure point, apply a targeted fix, verify it resolves cleanly and explain what went wrong so it doesn't happen again. No generic scripts, no guesswork.
This service is built for founders, indie hackers and agencies who built fast with AI tools and now need someone who understands how Claude Code and Supabase talk to each other under the hood. Stop losing clients and momentum to a bug you cannot pin down.
Order now, let's get your backend working again today.

FAQ
What kind of errors can you fix?
Row Level Security (RLS) policy violations, authentication and JWT misconfigurations, MCP connection issues in Claude Code, failed Supabase edge function deploys, broken database migrations, and v0-generated frontend errors that break on launch.
Do I need to give you full access to my project?
Not always. In most cases, I only need read access to your repo, your Supabase project, and the specific error logs or screenshots. I'll tell you exactly what access is needed before starting, and you control what you share.
My app was fully "vibe coded" with AI, will you understand it?
Yes. I specialize in AI-generated codebases built with Claude Code, v0, and Supabase, so I'm used to reading and untangling AI-written code, not just traditional hand-coded projects.
How fast can you actually fix this?
Most single-bug fixes (Basic) are delivered within 24-48 hours. Standard (up to 3 bugs) typically takes 2-3 days. Premium full-backend audits may take 3-5 days depending on scope.
What if you can't find the root cause?
I diagnose before I fix, and I'll tell you honestly if something needs more investigation or isn't within scope before starting work, so you're never billed for guesswork.
Do you fix issues even if my Supabase project uses Row Level Security?
Yes — RLS policy debugging is one of the most common issues I handle. Misconfigured policies are usually the actual root cause of "permission denied" or "unauthorized" errors buyers report.
Can you also fix frontend issues from v0, not just backend?
Yes. Many "backend" errors actually stem from a mismatch between your v0-generated frontend and Supabase's expected data structure or auth flow — I check both sides.
Will you explain what caused the bug, or just fix it silently?
I always explain the root cause and the fix in plain language, so you understand what happened and can avoid it recurring, not just receive a black-box patch.
What if I have more than 3 bugs or need ongoing support?
Go with the Premium package for unlimited fixes in one audit, or message me about a monthly retainer if you want ongoing Claude Code/Supabase maintenance support.
Do you offer revisions if the fix doesn't fully resolve the issue?
Yes — if the specific bug we agreed to fix isn't fully resolved, I'll continue working on it at no extra cost until it's confirmed working on your end.
