FAQ

Questions I Get Asked

If you're here, you probably vibe coded something and it went sideways. Here's what you need to know.

Can you fix my vibe coded app?

Yes. I specialize in fixing apps built with AI tools like ChatGPT, Cursor, Copilot, Lovable, Bolt, Replit, and v0. Broken features, messy architecture, security holes. I clean it up and make it production-ready.

My ChatGPT / Cursor code has bugs I can't fix. Can you help?

Absolutely. AI-generated code often has subtle bugs, security flaws, and architectural issues that compound over time. I debug the root cause, fix the issues, and restructure the code so it's maintainable going forward.

How fast can you fix a production bug?

Most emergency fixes are resolved within 24 to 48 hours. I offer emergency debugging starting at $300 for critical production issues that are blocking your launch or affecting live users.

I hired someone on Fiverr / Upwork and the code doesn't work. Can you rescue it?

Yes, code rescue is one of my most popular services. I audit the existing codebase, identify what's broken, fix critical issues, and refactor the code into something your team can actually maintain and build on.

I used Lovable / Bolt / Replit and hit a wall. Now what?

Those tools are great for prototyping, but they often produce code that breaks when you need real features, authentication, payments, or scale. I take over where the AI left off, fix what's broken, and build out what's missing properly.

Do you build apps from scratch too?

Yes. iOS apps, web apps, landing pages, full-stack MVPs, and APIs. From idea to shipped product, I handle it end to end.

How much does it cost?

It depends on the scope. Emergency debugging starts at $300, security audits start at $1,000, and full builds are scoped per project. Reach out with what you're dealing with and I'll give you an honest estimate.
