About this gig

Built an app with Lovable, Bolt, Replit, Base44, Cursor, v0, or Claude Code, but it breaks under real use? I will fix and productionize your vibe-coded React or SaaS app.


As a senior JavaScript engineer, I turn AI-generated prototypes into stable, maintainable products.


I can help with:

Bug diagnosis and scoped fixes

React, Next.js, Node.js, Express, and TypeScript

Authentication, authorization, and API security

Supabase, MongoDB, PostgreSQL, or Firebase issues

Stripe subscriptions and webhook reliability

Code cleanup, validation, error handling, and performance

Tests, environment setup, CI/CD, and deployment


You receive clean source code, a change summary, testing notes, and handover documentation.


Best for founders and teams whose MVP is nearly working but not safe or reliable enough to launch.


Basic covers an audit or tightly scoped rescue. Standard and Premium cover agreed issues within a defined codebase. New features, redesigns, mobile builds, and major rewrites need a custom offer. Please share your stack, repository summary, and issue list in Fiverr chat before ordering Standard or Premium.

I help founders turn fragile prototypes and single-customer web apps into secure, maintainable SaaS products. My focus is React, Node.js, Express, TypeScript, MongoDB, PostgreSQL, authentication, Stripe billing, MCP integrations, API architecture, and multi-tenant systems. I can rescue AI generated apps, connect AI clients to business systems through secure MCP servers and convert existing products into organization based SaaS platforms with isolated data and rolebased access. My deliveries include source code, testing notes, clear documentation, and honest reporting of remaining risks.
