FAQ
Which vibe coding platforms do you support?
Lovable, Bolt, Replit, Base44, Cursor, and v0 by Vercel. If your app was built by an AI builder or a no code tool and something broke, I can fix it regardless of the platform.
What if I don't know exactly what's broken?
That's fine — most clients don't. Share a description of what's not working, a screenshot, or a Loom recording. I'll diagnose the issue and give you a clear fix plan before we start.
Can you add features my vibe coding app couldn't generate?
Yes. AI builders hit limits fast — complex logic, third-party APIs, custom auth flows. I write the code your builder couldn't, clean and production-ready.
Will you fix my app without breaking what already works?
Always. I review the full codebase before touching anything. Every fix is isolated so existing functionality stays intact.
How fast can you fix a bug?
Simple bugs are fixed within 24 hours. Complex issues or multi-bug projects take 2–3 days. The premium package covers full overhauls within 7 days.
