I will fix your supabase auth rls policy and database connection errors
I fix broken Nextjs Supabase Stripe and AI built apps and deployments
Most of what I do is fix things other people built. A Lovable or Base44 app that stalled at 80 percent. A Next.js app that runs locally and dies on Vercel. Supabase auth that works in preview and fail...
About this Gig
Supabase login not working, or an RLS policy blocking queries that should work? I fix auth flows, row level security and connection errors, usually the same day.
RLS bugs look bigger than they are. Too strict, and your own users get empty results with no error. Too loose, and anyone with your anon key can read the whole table. Both look fine locally.
Then there's auth. Signup works, login silently fails, usually a redirect URL pointing at an environment that doesn't exist anymore.
What I usually fix
Login, signup and magic link flows that fail silently
RLS policies blocking legitimate queries
RLS gaps that expose data they shouldn't
The classic new row violates row level security policy error
Connection drops and pooling errors under load
Broken OAuth with Google, GitHub and others
Storage bucket permissions and upload failures
Migrations that won't apply cleanly
Empty results aren't always RLS, so I check the query, session and data before touching a policy, then test both sides, the user who should see the row and the one who shouldn't.
Send your error or a screenshot of the policy and I'll tell you what's going on before you order.

FAQ
My app was built by Lovable or Base44. Can you fix the Supabase side of it?
Yes, that's a large chunk of what I deal with. AI tools tend to generate Supabase code that works fine in preview and then breaks once the project goes live.
My queries return empty with no error at all. What's going on?
Usually it's RLS. The policy quietly blocks the row and Supabase just returns nothing instead of throwing an error. I also check the session and the query itself, because a wrong filter can look identical from the outside.
Will you need my database credentials?
Just project access. Send a temporary collaborator invite instead of your service role key, and remove it once I'm done. Keep keys out of chat entirely.
Can you check whether my data is actually secure?
The Premium package checks every table for gaps where the anon key could read or write something it shouldn't. Think of it as a policy check on your tables, not a full security certification of the whole app.
What if the problem is actually in my app code, not Supabase?
I'll fix it either way. I work in Next.js and React too, so I won't hand it back to you at the boundary.
