I will add stripe payments, authentication and supabase to your next js app


Level 1
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}.

FAQ
Can you work with an existing codebase or do you start from scratch?
Existing codebases are fine — that's the main use case. Share your repo before ordering and I'll confirm I can work with your setup without rewriting what's already there.
Do I need my own Stripe, Supabase and Clerk accounts?
Yes — you'll need accounts on the services you want integrated (all have free tiers that cover development). I'll handle the implementation; you keep ownership of all credentials and data.
What if my app uses a different framework or stack?
Message me before ordering with your stack details. I work primarily in Next.js and React — if your setup is compatible I'll confirm it, if not I'll tell you upfront rather than take an order I can't deliver well.
