Your app was built fast with Lovable, Bolt, v0, Replit, Cursor or Claude Code, and now something is wrong: login fails, payments do not go through, the build will not deploy, or you are not sure it is safe for real users. I fix that.

Find and fix bugs in React, Next.js, Node and Python code

Repair login, Supabase or Firebase rules, and Stripe payments and webhooks

Move the project to GitHub and deploy it to Vercel, Netlify or your own server

Check for exposed keys, open database tables and other common security holes

Finish the parts the AI tools left half done

Every fix comes as a separate commit with a short note on what was wrong and why, so the next change does not break it again.

I use AI coding tools every day myself, so I know where they cut corners and how to make their output ready for production.

Everything happens in writing, no calls needed. Send the task, the deadline and the budget, and I reply the same day.
