Need a developer to fix your AI-built app? I make it ready for paying customers, without a rewrite.
Start with a $299 Launch Check: in 48 hours I check your live app, fix the three biggest problems, and send you a written report and a video. Then, if you want everything done, a fixed-price Sprint makes it production-ready in 5 days.
- Report, video and top 3 fixes in 48 hours
- Fewer than 3 real problems fixed? Full refund
- Collaborator access only, never your passwords
Something broken right now? Start a Rescue: I begin within 24 hours.
The ten things AI builders leave out
Lovable, Bolt and the rest get you to a working demo fast. Production is a checklist they don't show you. This is mine. A Launch Check goes through all ten on your live app.
Database rules
Each customer can only read and change their own rows.
Secrets
No secret key reaches the browser or the repository.
Payments
Access is granted and removed only by verified Stripe webhooks.
Who can call what
Every route and function checks who is asking, not just that they're signed in.
Sign-in emails
Confirmations and resets arrive, from your domain, linking to your domain.
Your domain
One address with HTTPS; redirects and callbacks all point at it.
Backups
A nightly backup kept elsewhere, and one restore actually tested.
Error monitoring
You hear about a crash before a customer tells you.
Uptime alerts
You get a message within minutes if the site goes down.
Limits
Sign-up, forms and AI calls are rate-limited so nobody can run up your bill.
Works with Lovable, Bolt, Replit, Cursor and v0, and anything else with a code repository. Not affiliated with any of these builders.
What you get in 48 hours, for $299
A written report
All ten areas marked pass, warning or fail, what each failure means for your customers in plain words, and what it takes to fix.
A 10-minute video
Me walking through your app and the report, so you understand what I found without reading code.
The 3 biggest problems, fixed
Done in your repository as changes you approve, each with a short note on what changed and why.
A list of keys to rotate
Every secret that may have been exposed, where to rotate it, and in what order.

- 5 minutes
Give me access
Your app's address, and collaborator access to GitHub, Supabase and your hosting. Never passwords.
- Within 48 hours
Report, video, 3 fixes
I check all ten areas on your live app, fix the three most serious problems, and send the report and video.
- Your call
Stop there, or finish the job
Fix the rest yourself with the report, or book the 5-day Sprint with the $299 taken off.
You don't carry the risk
Launch Check: 3 real fixes, or your money back
If I can't find and fix at least three real problems in your app, you get the full $299 back. You keep the report.
Sprint: live in 5 working days, or your money back
If the Sprint isn't live in 5 working days from the day I have access, you get the full $1,090 back, and you keep everything I finished.
What I won't do is call your app "secure": nobody honestly can. You get, in writing, what I checked, what I fixed and what's still open. Refund policy.
Why not just ask the AI, or hire a freelancer?
| What matters | Launch Check with me | Ask the builder's AI | A report-only audit | Hire a freelancer |
|---|---|---|---|---|
| Problems fixed, not just listed | Top 3 fixed in 48 hours | Sometimes | No | Yes |
| Price known before you start | $299, fixed | Credits, until it works | Yes | Usually hourly |
| Checks your live database and Stripe, not just the code | Yes | No | Depends | Depends |
| Keeps your builder and your code | Yes, no rewrite | Yes | Yes | Often quotes a rewrite |
| Money back if it doesn't deliver | Yes | No | Rarely | Rarely |

Questions
What do you need from me to start?
After you pay, a short form: your app's address, which builder you used, and access to the GitHub repository, the database project and the hosting, as a collaborator. I never ask for your passwords.
Can you guarantee my app is secure?
No one honestly can. I guarantee the checklist: you get, in writing, what I checked, what I fixed and what is still open, and every fix is a change you can read.
What if the Sprint isn't live in 5 working days?
You get the full $1,090 back. The 5 days start when I have access to everything on the intake form.
Does the Launch Check count toward a Sprint?
Yes. The full $299 comes off the Sprint if you book it within 14 days of the report. A Rescue counts the same way.
Which builders do you work with?
Lovable, Bolt, Replit, v0 and apps written with Cursor or Claude Code. If yours is something else and has a code repository, ask me.
Is it safe to give you access?
You add me as a collaborator on GitHub, Supabase and your hosting, so you can see everything I do and remove me in one click. I never ask for passwords, I don't copy your customers' data anywhere, and when I'm done you get a list of keys to rotate.
What if you don't find much?
If I can't find and fix at least 3 real problems, you get the $299 back. You still keep the report, which shows what was checked and passed.
Will you rewrite my app or make me leave my builder?
No. I fix what's there, in your repository. You keep building in Lovable, Bolt or Replit afterwards, and the report tells you what not to undo.
Who does the work?
I do, myself, every check and every fix. That's why there are only three Sprint slots a week.
Is this a penetration test?
No. I check your app's setup against a fixed list, on your own accounts, and fix what fails. I don't attack your app or anyone else's, and I won't call it "secure": you get in writing what was checked, what was fixed and what's still open.
Where are you, and how fast do you reply?
I work from Europe (CET) and reply to email within a few hours on working days. The 48 hours of a Launch Check start when I have access; a Rescue starts within 24 hours, any day.
What happens after the Launch Check?
Nothing, unless you want it to. The report is yours to fix the rest yourself or with anyone. If you book the 5-day Sprint within 14 days, the $299 comes off its price.
Find out what your app is missing, in 48 hours
A Launch Check is $299: a written report, a video walkthrough and the three biggest problems fixed. Fewer than three real fixes and you get your money back. The full price comes off a Sprint booked within 14 days.
