You will get one bug fixed in your AI-built app, verified and explained
Project details
Built an app with Lovable, Bolt, Cursor, v0 or ChatGPT and now one thing is broken? I fix one specific, reproducible bug and prove it's actually fixed.
You get:
• the failing case reproduced first, then passing
• the smallest fix that resolves it (no unnecessary rewrites)
• a short plain-language handover: what was wrong, what I changed, how I verified it
Good fits: a route that 500s, a broken login/auth flow, a Supabase or database error, a failed Vercel deploy, a webhook or API call that doesn't work.
This package is one clearly-scoped bug. If you have several, message me first and we'll scope it together.
I keep repo access minimal and never need production secrets or customer data for this.

About Sebastian
AI-Built App Broken? I Fix & Ship Next.js / Supabase / Vercel Apps
Sindelfingen, Germany - 11:09 pm local time
That's exactly what I fix. I take broken or half-finished AI-built React/Next.js + Supabase apps and get them working again - scoped and fast, without rewriting your whole project.
What's different: every fix ships verified, not "should work." I reproduce your exact bug first, fix it, then prove it's gone - the failing case passes, the app still builds and runs, nothing else broke. You get a short plain-language handover: what was wrong, what I changed, and how it was verified. No black box.
Good fits: a broken or failing route, auth/login issues, Supabase or database errors, a failed Vercel deploy, a webhook or API call that doesn't work, a repetitive task that should be a script.
To start I need: repo access (GitHub), what should happen, the current error or a screenshot, and how to run it. I keep access minimal and never touch payments, secrets, or customer data beyond what the fix needs.
