I will fix vibe coded app bugs errors rescue flutter nodejs sveltekit firebase supabase

Your app was built fast with AI tools like Lovable, Bolt, Replit, or Cursor. It worked fine in the demo. Now, it crashes, throws errors, or breaks the moment real users touch it.

This happens because AI generated code often skips error handling, security checks, and real testing. I read closely through your codebase, find the true root cause of each bug, and fix it properly instead of patching symptoms so it stays fixed.

What you get:

• Full review of your Flutter, Node.js, or SvelteKit codebase
• Every crash and error found and fixed
• Clean working code that matches how your app should behave
• A short report explaining what broke and why
• Basic testing before I hand it back
• Clear notes so you or your next developer can maintain it

Tools I work with:

• Flutter, Dart, Firebase, and Supabase for mobile apps
• Node.js, Express, NestJS, and PostgreSQL for backends
• SvelteKit, Svelte 5 runes, and Vercel for web apps
• Stripe, JWT auth, and REST or GraphQL APIs when needed

Send me your codebase and a full list of what is going wrong. I will tell you honestly if I can fix it before you pay me a cent.
