About this gig

Got a Next.js app that needs real payments, login and a database fast? Stripe, Clerk and Supabase, wired in properly and deployed, without breaking your existing code.


Working in Next.js, React and TypeScript with Stripe, Supabase (Postgres + RLS), Clerk and Vercel the exact stack modern SaaS apps run on.


What you get:

- Stripe Checkout, subscriptions and webhooks that handle real payments securely

- Authentication with Clerk or Supabase Auth, including protected routes and roles

- Supabase Postgres setup with schema, migrations and Row Level Security

- API routes and third-party integrations wired into your app

- Stuck on a Lovable, Bolt, v0 or Cursor MVP? I'll finish it and deploy to Vercel

- Clean, documented TypeScript you (or your next dev) can maintain


I add features to existing codebases without rewriting what already works, and I test payment and auth flows end to end before handing back.


Send me your repo or a description of your app before ordering and I'll confirm scope and timeline the same day {username}.
