I will built this exact flow

I build production-grade multi-step forms with Stripe payment and real-time validation the kind your customers can actually complete without abandoning.

I don't ship create-react-app with inline styles. I ship clean Next.js (App Router) with real validation, error handling, mobile responsiveness, and Stripe wired end-to-end.

What I can build:

Multi-step forms (210 steps) with progress indicator and saved state

Stripe one-time payments or subscriptions

Firebase Authentication (email/password, Google) with protected routes

Form data saved to Firestore so you never lose a lead

Conditional logic (show/hide fields based on answers)

A basic admin dashboard to view submissions

I've built this exact flow in production a live 4-step registration funnel with Stripe payments. I treat your project like it's going to production, not a demo.

You describe the steps and fields; I build, validate, deploy, and walk you through it.
