Work, crafted.
Make your app production-ready.
I build, fix and automate full-stack apps — Next.js, Supabase, Stripe and AI. Fixed prices. Written updates. You own the code.
Who it’s for
Three situations I see most.
Your AI-built app is stuck
A Lovable, Bolt or Base44 app that breaks, leaks data or won’t deploy.
Best fit: Rescue
Your developer left
A live app with nobody to maintain it.
Best fit: Rescue, then Care
You need something new
A custom app, MVP or AI automation.
Best fit: Build or Automate

FAQ
Questions before you start.
Will you rewrite my app?
No. The audit lists what changes and what stays.
Can I keep building in Lovable or Bolt?
Yes. Changes go through GitHub with notes.
Who owns the code?
You do, in your own repo, from day one.
Do you sign an NDA?
Yes.
How do payments work?
Upfront, by invoice.
What if you find more problems?
You get a separate written quote first. Nothing extra is billed without your OK.

What projects don’t you take?
Gambling, crypto speculation, interest-based lending, MLM and adult content.
