About this gig

Your Replit app should work like a real product, not a project stuck in the sandbox.


I help founders and small businesses fix, finish, and scale Replit apps turning half-working builds into stable, launch-ready MVPs and SaaS products.

Most clients come to me after quick fixes run out broken auth, database errors, silent payment failures, deployment issues, or an app that works in the editor but breaks for real users. I find the root cause instead of patching around it.

I work across React, Node.js, Supabase, PostgreSQL, and Stripe so I'm not limited by what Replit's built-in tools alone can do.


What I help with:

  • Replit app debugging auth, database, broken logic
  • Replit Stripe and payment integration
  • Replit database setup (Supabase/PostgreSQL)
  • Replit full MVP/SaaS builds from an existing project
  • Replit deployment Always On setup and Economy mode migration
  • Replit API and AI integrations
  • Replit app audits a clear report on what's broken

If you want an expert to work on your app/website..send a message and let discuss your project
