I will fix lovable app bugs supabase authentication deployment errors
Stuart Crabtree
About this gig
A Lovable app can look finished long before it's ready for real users. What happens when sign up keeps looping, data won't save, or the published app behaves differently from the preview? Suddenly, your launch is stuck.
I troubleshoot existing Lovable apps connected to Supabase. I will reproduce the bug, check authentication, redirect settings, database queries, RLS permissions, or deployment logs as needed, then repair the agreed issue and test the affected user flow. You'll get a clear summary of what caused the problem, what changed, and how the fix was checked.
What I Will Fix
- Lovable app bugs, broken pages, buttons and forms
- Supabase login, signup and password reset issues
- RLS errors, database queries and access permissions
- API connections, session and redirect problems
- Failed builds, publishing and deployment errors
I focus on targeted fixes without unnecessary rebuilds or disabling security protections to hide an error.
Let's get your app working as intended. Send your app link, a screenshot and what happens versus what should happen.

FAQ
My Lovable app lets users sign up, but keeps sending them back to the login page. Can you fix that?
Yes, I can investigate that. Sometimes the issue comes from session handling, authentication callbacks, redirect settings, or protected routes. I'll check how your Lovable app communicates with Supabase, trace the login process, and repair the identified issue within our agreed scope.
Why does my Lovable app work in preview but stop working after I publish it?
Preview and live environments can use different domains, redirect URLs, environment settings, or deployment configurations. I'll compare the relevant settings, check the available error logs, and troubleshoot what's causing the live version to behave differently.
Supabase keeps showing permission denied or RLS errors. Can you fix this without exposing my data?
I can review the affected database permissions and Row Level Security policies to identify why legitimate requests are being blocked. I won't simply disable RLS to make an error disappear. Any changes will be tested against the access rules your app is supposed to enforce.
Will you need to rebuild my entire Lovable app or change features that already work?
Not necessarily. My first step is to reproduce the issue and understand what caused it. I'll focus on the agreed repair and avoid unnecessary changes. Where possible, I'll use backups or a safe testing environment before modifying your live app.
What if you discover that my Lovable app has more problems than I originally reported?
I'll explain what I've found and which issues fall outside the package you purchased. We can agree on the additional work and price before proceeding. You'll also receive an explanation of the completed changes and testing.
