v0 app fixes · fixed price
Finish your v0 app.
v0 is very good at screens. What it hands you often looks finished and isn't: the data is sample data, the forms don't send, there's no login, and the Vercel build fails on errors the preview never showed. I read the code, list what's missing or broken, and give you a fixed price per item.
v0 writes Next.js with React, Tailwind and shadcn/ui, and deploys to Vercel. Next.js is my main framework, so I'm working in the code it was designed for, not around it.
Common problems
What usually goes wrong.
It looks finished, but the data is fake
v0 fills screens with sample data so they look right. Connecting them to a real database (Supabase, Postgres or your API), with loading and empty states, is the actual build.
The forms don't do anything
The form is there; the code that receives it isn't. It needs a server action or API route, validation, a confirmation email, and somewhere for the submission to go.
There's no login, or anyone can open the admin pages
Generated pages usually have no access control. Users, sessions and protected routes have to be added, and checked on the server, not just hidden in the menu.
The build fails on Vercel
Type errors, missing environment variables, or browser-only code running on the server. The preview is more forgiving than a production build.
Errors about server and client components
Interactive code placed in a server component, or a page that renders differently on the server and in the browser. Each one is a small, specific fix once found.
Payments, emails or uploads aren't wired up
The buttons exist; the integrations behind them don't. Stripe webhooks, email sending and file storage each need real setup and testing.
Something else? Most problems don’t fit a list. Describe it in two lines and I’ll tell you whether I can fix it.
Price
Fixed before anything starts.
Diagnosis
You send the repo and what's broken. I read the code and send back a written list: what's broken, how serious, and a fixed price per item.
$249
credited to the fix
Delivery: 48 hours
Fix pack
Broken auth, failed deploys, forms that don't submit, layouts that fall apart on mobile, features the AI left half-done. Moving to a new host counts as an item.
from $750
items quoted after diagnosis
Delivery: 2–5 days
The diagnosis fee is credited against the fix (minimum fix order $750), and refunded in full if nothing is worth fixing.

A fixed price in writing
New builds get a written scope and price. Existing apps get a $249 diagnosis in 48 hours: each problem, how serious, and a price to fix it.
- 03
You pick what to do
A deposit for the items you choose: 50%, or 30% on longer jobs paid by milestone. The diagnosis fee is credited.

Built, then handed over
A preview link to check first. The balance on handoff, and the code is yours.
Questions
About v0 fixes.
Can I keep using v0 after you finish it?
Yes, for new screens. I'll keep its structure and components so new v0 output still fits, and tell you which files to leave alone.
Is this a fix or a build?
Often a bit of both: fixing what's broken and wiring up what's only drawn. The diagnosis separates the two and prices each item, so you choose what to do now.
Will it stay on Vercel?
If you like. I'll set up hosting, the database and the environment in accounts you own, so nothing depends on me.
Will you sign an NDA before seeing my code?
Yes. Send yours and I'll sign it before I see the repo. Your app and your name stay private.

Guides
Try it yourself first.
- Login works in the preview but fails on your domain
Supabase only sends people back to addresses it has been told to trust. Move to your own domain without telling it, and confirmation links, password resets and Google sign-in all land somewhere else.
- Is my Supabase data public? How to check in 10 minutes
Apps built with Lovable, Bolt and similar tools talk to Supabase straight from the browser. That's normal, but it means one setting decides whether a stranger can read your users' data.
Send me your v0 app.
Two lines and a repo link. I reply within 24 hours (Mon–Sat) with the $249 diagnosis invoice, or tell you straight away if it isn't something I can do well.
