About this service

Summary

I help clients finalize and launch their Vibe Coded/Lovable/Saas apps by fixing bugs, optimizing workflows, reviewing integrations, and preparing the app for a clean, stable deployment.
With experience in automation (n8n), backend development, APIs, Supabase, and modern app architecture, I can take an almost-finished project and make it production-ready. If you want someone who works fast, communicates clearly, and delivers polished results, I’m the right fit.

What's included

  • Full App Bug Fixing

    Identify and resolve logical errors, broken flows, loading issues, and unexpected behaviors that prevent the app from working properly.

  • Responsive Layout Overhaul

    Fix mobile, tablet, and desktop responsiveness to ensure all screens adapt correctly across different devices.

  • Integration Review & Fixes

    Audit and repair all external integrations (APIs, webhooks, Supabase, Stripe, etc.) to fix authentication problems, inconsistent calls, and sync issues.

  • Final Deployment Support

    Assist with configuration and deployment to your chosen environment, ensuring a smooth and successful launch.

I've worked with Cristian Anterior for two years, and he is one of the best professionals I have ever worked with. I'm proud to say that he is extremely smart, responsible, and efficient. We worked together developing web applications in Angular, ASP.NET, and .NET, which were used by many companies and achieved outstanding results.
