I will integrate stripe payments into your nextjs app with checkout and webhooks
Denys K.
About this gig
I wire Stripe into an existing Next.js app so payments work end to end and your database always agrees with Stripe.
What I do: Stripe Checkout or the Payment Element on your pages, a webhook endpoint with signature verification and idempotent handling, and entitlements written into your own database (Supabase, Prisma or Postgres) so access is granted by the server and not by the browser. Everything is built and verified in test mode first, then you switch to live keys with a short checklist.
Stack: Next.js, React, TypeScript, Node, Prisma or Supabase, PostgreSQL, Vercel.
How it works: everything happens in writing, async, no calls needed. You invite me to the repo on GitHub, I deliver a pull request plus a short written summary of what changed and how to verify it. I build and run my own products on this stack: a real-time multiplayer board games platform with Stripe subscriptions and 1500+ automated tests, and a Norwegian overtime pay calculator.
Not included: building the app itself, and tax or accounting advice.

Full-stack developer (Next.js, React, TypeScript, Node, PostgreSQL) based in Norway. I fix bugs, ship features and wire payments and auth into existing apps: Stripe subscriptions and one-off checkout, Supabase and Prisma data layers, NextAuth, webhooks, cron jobs on Vercel. Python for automation: scrapers, data transforms, scheduled reports to email or Telegram. I work async and in writing: you send a clear brief, I send back a scoped estimate the same day, then a delivery with a short summary of what changed and how to verify it.
FAQ
Do you build it in test mode or with live keys?
Everything is built and verified in Stripe test mode. You switch to live keys yourself with a short checklist I send with the delivery.
Do we need a call?
No. Everything is handled in writing: you send the brief and repo access, I send back the scope, then a pull request with a summary of what changed and how to verify it.
