I will fix bugs in your vibe coded react and python web app
Sajjad Ali
À propos de ce service
Stuck with bugs in your React, Next.js, or vibe-coded app (Replit, Lovable, Bolt, Cursor)? I find and fix them fast with clean, working code and no shortcuts.
I specialize in debugging full-stack apps, including React/Next.js frontends, Python (Django/FastAPI) backends, and AI-integrated applications.
What I fix:
- Console errors, crashes, and broken UI
- API and backend logic errors
- Authentication, database, and state management bugs
- Performance issues slowing your app
- AI/LLM integration bugs (OpenAI, Gemini, Claude)
Why choose me?
- 2+ years of production experience with Django, FastAPI, and React
- Built and shipped real AI and backend systems, not just tutorials
- Fast, clear communication. I explain the fix, not just apply it
- On-time delivery, every time
Send me your error or repository, and I'll tell you what's wrong before you order.
Let's get your app running smoothly again!
