I will vibe code, fix, and secure your lovable, bolt, or supabase saas mvp
Joshua K.
About this gig
Are you tired of fighting with broken AI prompts? Vibe coding with Lovable, Bolt, or Replit is incredibly fast for prototyping, but AI-generated code frequently breaks down when handling user authentication, relational databases, or custom API deployments.
As a full-stack engineer, I bridge the gap between rapid AI speed and stable, production-ready software. I don't just prompt, I optimize the underlying React code, secure your Supabase backend, and make sure your app actually holds up for real users.
What I deliver:
- Full MVP Development: Clean, functional SaaS apps built at lightning speed.
- ️ Expert Bug Fixing: Resolving broken React state, API failures, and routing loops.
- Supabase & Security Setup: Bulletproof database architecture and RLS policies.
- Integrations & Deployment: Stripe subscription gates and live domain launches.
Stop losing hours trying to debug automated code. Let a human engineer finalize your application so you can focus on your launch.
Message me with your project details before ordering!

FAQ
How do we handle platform subscriptions (Lovable, Supabase, etc.)?
To ensure you maintain 100% ownership of your code and data from day one, you will invite me as a collaborator to your personal Lovable/Replit workspace and Supabase project.
What counts as a "Screen" in the Standard and Premium packages?
A screen is a distinct, functional view in the app (e.g., Landing Page, User Dashboard, Settings Modal, Login Page). We will map out exactly which screens are included during our initial project kickoff.
Can you fix my app if it was built with a different AI tool?
Yes. Whether it was built with Lovable, Bolt.new, Cursor, or v0, the underlying code is usually React or standard web languages. I can step in, audit the codebase, and apply the necessary fixes.
Do you offer unlimited revisions?
I offer focused, structured revisions based on the package tier. To maintain fast delivery times (3 to 6 days), we agree on the core features before starting. Any massive changes to the project scope after development begins will be handled via custom add-ons.
