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

FAQ
My app was built by someone else can you still fix it?
Yes. Most clients come to me with Replit projects they didn't originally build with me. Send me the project link and a note on what's wrong, and I'll take it from there.
Do I need to give you access to my Replit project?
Yes I'll need edit/collaborator access (or an invite to the Repl) to diagnose and fix issues properly. I'll only use it for the agreed scope.
My app works in the editor but breaks when deployed why?
This is one of the most common issues I see. It's usually caused by missing environment variables/secrets, database connection limits, or deployment config that differs from your dev environment. I find the actual cause and fix it.
Can you help reduce my Replit hosting costs?
Yes I can review your deployment setup and migrate you to Economy mode where it fits, or optimize your Always On configuration so you're not paying for more than you need.
Can you add Stripe payments to my existing Replit app?
Yes full Stripe setup including one-time payments, subscriptions, and webhook configuration, tested end-to-end before handover.
How fast can you begin?
I can usually begin within 24 hours of receiving project access and a clear description of the issue.
