Fixing apps built with AI

Your app was built with an AI tool or by vibe coding, and it works — more or less. I review the code, find the bugs and the risky parts, then help you fix, stabilise and prepare it for real use.

When to come to me with this

  • The prototype is done, but you do not dare let real customers use it.
  • Every fix breaks something else, and the AI tool goes round in circles.
  • You are not sure where the passwords, keys and customer data are, or who can reach them.
  • It got slow as the data or the number of users grew.

What it includes

  • a code review and written summary: what is risky, what can wait, what is fine
  • debugging, fixes and performance work
  • security: permissions, keys, handling customer data
  • more maintainable code, so the next change does not break something else
  • help with going live and running it

How it works

The review is billed hourly within an agreed budget, so you know the cost upfront. Then you decide whether I do the fixes, or you continue with your AI tool using the list.

Price

For larger projects I give a fixed price split into milestones. Day rate: HUF 100–120k, hourly: HUF 17,500. The first hour is free: we talk through what you need.

Questions

Does the whole thing need rewriting?

Rarely. Usually a few parts cause most of the trouble (permissions, data handling, error handling); we fix those and keep the rest.

Thinking of something similar?

Write a few lines about what you want to solve, and we will work out the best next step. The first hour is free.
