I will fix your lovable webapp, debug vibecoding, supabase and vercel deployment errors
Stella J
About this gig
Built your app with Lovable, but now it has bugs, broken features, Supabase errors, failed API connections, or Vercel deployment issues?
I help founders fix, finish, and launch Lovable web apps without unnecessary rebuilding. Whether your vibe-coded app has login problems, database errors, payment failures, mobile responsiveness issues, or a build that will not deploy, I will diagnose the root cause and provide a clean, practical solution.
What I can help with:
- Lovable app bug fixing and debugging
- Supabase database, auth, RLS, and connection errors
- Vercel deployment, build, domain, and environment variable issues
- Stripe, webhook, and third-party API integration
- Broken forms, dashboards, buttons, and app functionality
- AI-generated code cleanup and production-readiness checks
You will receive clear communication, defined scope, tested fixes, and a simple handover explaining what was repaired. I work carefully with your existing code and only change what is necessary.
Please message me before ordering with your app link, error details, and the issues you need fixed. I will review the scope and recommend the right package.

I'm Jonathan Stella, i started building web applications after seeing how small bugs could stop businesses from making sales. What began as fixing login issues and broken deployments quickly became a passion for building reliable, scalable web solutions. Today I help startups, agencies, and business owners solve complex Nextjs, Payload CMS, Supabase, Stripe, and Vercel challenges with clean, production ready code. I believe every project deserves clear communication, dependable delivery, and solutions that keep growing long after deployment. My goal is simple. Build it right the first time.
