FAQ
What do you need from me to get started?
GitHub repo link (or zip file), description of the bug or issue, and access to your Supabase project if needed.
Can you fix apps built with Lovable, v0, or Bolt.new?
Yes — that's exactly what this gig is for. AI-generated code has common patterns I know how to debug quickly.
What if the bug is more complex than expected?
I'll message you first with an updated quote. No surprise charges.
Do you fix deployment issues on Vercel?
Yes, covered in Standard and Premium packages.
Will you explain what was wrong?
Always. I send a short summary of what was broken and what I changed.
Have you ever built a vibe coded app yourself?
Yes! I have personally built and shipped apps using Lovable, v0, Bolt.new, and Cursor. So I don't just understand your code — I understand exactly how these AI builders think, where they make mistakes, and why certain bugs keep appearing. That's what makes fixing your app faster and more accurate.
What if you are unable to resolve my issue?
If I am unable to fix your issue completely, you will get a full refund — no questions asked. I will always be upfront with you before starting. If I feel the problem is too complex for the package you selected, I will tell you honestly before touching your code. Your money and trust both are safe
