I will fix replit supabase auth replit api error migrate replit to wordpress replit app
James Mix
About this gig
Built an app in Replit, but users can't log in, your Supabase data won't load, or deployment keeps failing? A broken backend can stall your launch even when the interface looks ready.
I provide targeted Replit bug fixes and Replit debugging for AI-built apps and SaaS projects. Instead of replacing your app, I trace the failing flow and repair the underlying issue.
What I can fix:
- Replit Supabase authentication, signup, session and Google OAuth login errors
- Supabase RLS "permission denied", database connection and data-saving issues
- Replit API integration errors, failing endpoints, webhooks and environment variables
- Replit deployment errors, production build failures and apps that break after publishing
- Backend bugs in React, Next.js and JavaScript/TypeScript projects
You get a clear diagnosis, a scoped fix, tests of the affected feature and a simple explanation of what changed. The goal: a working app you can confidently demo, launch or keep improvingnot another temporary patch.
Message me your Replit project link and the error screenshot before ordering. I'll review the issue and recommend the right package.

FAQ
Can you fix Replit apps that were built with AI?
Yes. I troubleshoot Replit AI-built apps and manually coded projects. I can trace errors across frontend, backend, Supabase and API connections. I focus on repairing the reported issue without rebuilding working features unnecessarily.
Can you fix Replit Supabase login and signup errors?
Yes. I can diagnose broken signup, login, Google OAuth redirects, expired sessions and Supabase authentication configuration. I'll inspect the relevant code, settings and error messages, then test the affected login flow after the fix.
Do you fix Supabase RLS and permission denied errors?
Yes. I investigate Supabase row-level security (RLS), permission denied messages and database reads or writes that fail. Any policy changes are scoped to the app's required access rules, not broad security bypasses.
Can you repair broken Replit API integrations?
Yes. I troubleshoot API request failures, incorrect endpoints, authentication errors, webhook issues and missing environment variables. I'll identify whether the fault is in your app, configuration or third-party service before proposing a fix.
Can you fix Replit deployment and production errors?
Yes. I investigate failed builds, runtime crashes, broken environment settings and differences between development and deployed versions. I test the affected feature after deployment where access and project configuration allow.
Will you rebuild my Replit app or change its design?
Not unless the repair requires it and we agree on the scope. My service targets bugs in your existing Replit app, Supabase backend, authentication, API integrations or deployment. Major redesigns and full rebuilds require a separate quote.
What do you need before starting my Replit bug fix?
Send the Replit project link, a screenshot or exact text of the error, steps to reproduce it and what should happen instead. Please use secure project access or share redacted logs. Never send passwords, private API keys or other secrets in chat.
How do you know what is causing my Replit error?
I reproduce the issue when possible, review relevant logs and code, and trace the failing authentication, API, database or deployment flow. I then explain the likely root cause, propose a scoped change and verify the result with a practical test.
Which Fiverr package should I order?
Basic covers one minor bug. Standard covers up to two related issues, such as Supabase auth and API errors. Premium covers up to three related issues, including deployment. Message me before ordering so we can confirm complexity and scope.
Do you test the fix and offer revisions?
Yes. Each package includes testing of the repaired feature and the revisions shown in the package. Revisions cover issues within the agreed scope; unrelated bugs or new features are quoted separately. I'll explain what was changed and any remaining limits.
