I will fix vibe coding errors and build your saas mvp or ai web app

About this gig
People don't pay for prompts. They pay for products.
If you built your app in Lovable, Replit, Bolt, Base44, or Cursor and it worked right up until a real user tried to sign up, pay, or refresh the page, that is not bad luck. That is what an AI-generated app looks like before someone makes it production-ready. I fix broken authentication, exposed API keys, database rules that let any user read another user's data, and features that pass the demo but fall over under real traffic.
If you have an AI-powered business idea and nothing built yet, I build the software around it. User accounts, dashboards, backend systems, databases, AI integration, payments, APIs, testing, and deployment within the agreed scope.
You don't need technical specifications or AI knowledge. Explain what your users should be able to do, and I will design and build the right solution.
Every project is scoped individually because no two SaaS products are the same. Message me before ordering with your idea, or a link to your broken app, and I will tell you what is wrong and what it will cost to fix before you pay anything.

FAQ
Can you fix an app I built with Lovable, Replit, Bolt, or Base44?
Yes, that is what the Fix & Stabilize package is for. Send me a link or a repo and I will tell you what is broken before you order. Most AI-generated apps fail in the same few places: authentication, database permissions, exposed keys, and payment flows.
My app works in the demo but breaks when real users try it. What is going on?
ery common with AI-generated code. The app was built to pass a demo, not to handle real traffic, concurrent users, or bad input. Usually it is missing database rules, proper error handling, and session management. All fixable, and usually faster than rebuilding.
Do I need to know what is wrong before I order?
No. Message me with a link and I will diagnose it for free and tell you which package fits. If it is a quick fix I will say so rather than sell you a bigger package.
Do I own the source code, and will I get documentation?
Completely. You own everything I build, handed over with clear documentation so you or any future developer can run and extend it without me.
Who pays for the AI usage, and will it cost me every month?
The AI runs on providers like OpenAI or Anthropic, which charge by usage. That cost is yours and goes straight to the provider, not to me. I set it up under your own account and give you a realistic estimate before we build, so nothing surprises you later.
Is my data safe when the app uses AI?
Yes. I build it so your data and your customers' data isn't used to train anyone's model, using the business-grade settings these providers offer. Your information stays yours.
Will you be available after the project is done?
Yes. I offer post-launch support and can stay on for fixes, changes, or new features. We agree how that works before delivery, so you're never stranded after launch.
