About this gig
Your Lovable app logs in fine on preview. Then you connect your real domain, click Sign in with Google, and it bounces the user back to localhost. Or it loops forever. Or it shows a blank screen after sign in. Sound familiar?
You've probably checked Google Cloud Console five times and burned Lovable credits telling the AI to fix the login, only to watch it break something else.
Here's the truth: it's almost never Google, and almost never your code. 9 out of 10 broken Lovable logins come down to your Supabase Site URL and redirect config, not your app. I fix the real cause.
WHAT I FIX:
- Sign in with Google sending users to localhost
- Login loop or stuck redirect
- Blank screen after sign in
- OAuth that works in preview but breaks on your live domain
- Email, password and social login setup
- Sessions that won't stay logged in
WHAT YOU GET:
- A working login on your LIVE domain, tested before handover
- A fix at the source, not a patch that breaks next week
- A short note on what was wrong, so it can't happen again
Send me your app link and the error FIRST. If it can't be fixed, I'll tell you before you order, so you waste nothing. Let's get your login working today.

FAQ
Do you need my Lovable or Supabase password?
No. You just invite me as a collaborator on your Lovable project and Supabase project. You stay in full control and can remove my access anytime.
What if my login can't be fixed?
It almost always can. But if I review it first and it can't be, I'll tell you before you order, so you never waste money.
Do you only fix Google login?
No. I handle Google OAuth, GitHub, email and password, magic links, session and JWT issues, and the Supabase and Lovable config behind all of them.
My app works in preview but breaks after I deploy. Can you fix that?
Yes. That preview versus production gap is the number one cause of a login that suddenly stops working, and it's exactly what I specialize in.
How fast can you fix it?
Most single login fixes are done within 24 hours of getting access. Send your app link and the error and I'll confirm the timing before you order.
