I will build a full stack nextjs saas mvp with stripe billing and auth


About this gig
You have an idea. I turn it into a real product your users can sign up for and pay for.
I am a senior full-stack developer who has shipped two AI SaaS products solo (SnapSkill and FlowSense) with real authentication, Stripe billing, and production databases. I do not hand you a template wrapper; I build a clean, deployable Next.js codebase that you fully own.
What you get is a Next.js and TypeScript app with Clerk authentication, a Postgres and Supabase database, a REST API, and a responsive UI, all deployed live to Vercel. Standard adds a CRUD dashboard and Stripe subscriptions with webhooks. Premium adds multi-tenant architecture, Stripe Connect, internationalization, automated tests with Vitest and Playwright, Sentry monitoring, plus a security and RLS review.
Every delivery includes the full source code and a Loom walkthrough so you can run, extend, and deploy it yourself. Message me your idea before ordering and I will confirm scope, timeline, and the right package for you.

FAQ
Do I own the code and can I host it myself?
Yes. You receive the full source code and it deploys to your own Vercel, database, and Stripe accounts, so you own and control everything with no lock-in.
What do you need from me to get started?
A short description of your idea, any designs or references you have, and access to your Vercel, database, and Stripe accounts when we reach deployment. We agree on the full scope in chat before you order.
How do you make sure it's production-ready?
Every build ships run against my 123-point production launch checklist - performance and Core Web Vitals, SEO, security headers, Supabase RLS, Clerk auth, Stripe webhooks, Sentry monitoring and accessibility - so you launch safely, not just quickly.
