About this gig
Your Lovable app looks fine until a user cannot log in, sees someone else's data, or a Supabase call throws a 401 with no clear reason why. That is almost always auth, RLS, or an API issue, not a frontend bug.
I fix exactly this layer: Supabase auth, row-level security, database access, and OAuth, the parts of a Lovable or AI-built app that break silently until a real user hits them.
Here is what I deliver:
- Supabase auth fixes: login, signup, session, redirect, password reset bugs
- RLS policy fixes: users blocked from their own data, or seeing data that is not theirs
- OAuth setup and debugging: Google, Facebook, and other social login integrations
- API integration: broken endpoints, missing headers, failed third-party calls
- Database bugs: table relationships, schema issues, permission errors
- Supabase integration from scratch for a new Lovable, Base44, or custom app
- Environment variable and API key errors between Supabase and your frontend
Most of what looks random is a specific policy, scope, or key that is wrong. I trace it there instead of guessing at the symptom.
Send your Supabase project, the exact error, and your app link. I will scope the fix before you order.

FAQ
What counts as 1 Supabase issue in the Basic package?
One defined problem: a login/auth bug, one RLS policy blocking or exposing data, one OAuth error, or one broken API call. More than that needs Standard.
My users can see data that is not theirs, is that an RLS problem?
Yes, almost always. That means a row-level security policy is missing or too permissive. I write and test policies scoped to your actual user roles.
Can you fix Google or Facebook OAuth login errors specifically?
Yes. Redirect URI mismatches, invalid client errors, and consent screen misconfigurations are the most common causes and the most common fixes I do.
Do you need my Supabase project access to diagnose this?
Yes, project or collaborator access is needed to see the actual RLS policies, auth settings, and API keys rather than guessing from a description.
Will you break other features while fixing RLS or auth?
I test every policy or auth change against your real user roles, not just the admin account, before calling the fix done, to avoid new breakage.
Is this only for Lovable apps or does it work with any Supabase backend?
Supabase, auth, RLS, and API issues are the same regardless of what generated the frontend. Lovable is my focus, but any React or Next.js app works.
What if the bug is not actually Supabase, is it something else?
That happens. If I trace it to a frontend or third-party issue outside Supabase, auth, or API scope, I will tell you before continuing the order.
Can you set up a brand new Supabase backend, not just fix an existing one?
Yes, that is the Premium package: auth, RLS policies, database schema, OAuth, and API integration built from scratch for a new or existing app.
How fast can you turn around a login or auth bug that is blocking users?
Basic package delivery is 2 days. If it is urgent and blocking your users right now, message me first and I will let you know if faster is possible.
What do you need from me to start?
Supabase project access, the exact error message or behavior, and your Lovable or app link so I can scope the fix accurately before you order.
