I will integrate stripe payment gateway in your node
Anatolii N.
About this gig
Need Stripe (or any payment gateway) integrated into your Node.js app the way you'd want it built if it was your money on the line?
I'm a senior Node.js engineer and Tech Lead at NovaPay (a major Ukrainian fintech), owning production payment-processing services every day. Payments aren't "just another API" for me they're my full-time job.
What you'll get:
- Stripe / PayPal / Square / Braintree / Adyen integration (Node.js, Express, NestJS, Next.js)
- Webhook handlers with idempotency, retries, and signature verification
- One-time payments, subscriptions, refunds, dispute handling
- Database design for payments, orders, and audit trail
- Error handling that doesn't silently swallow failed transactions
- Clean, commented TypeScript code you can extend
- Test mode setup + production deployment guide
Why me, not a $20 dev: payment bugs cost real money. I've seen the failure modes race conditions, double charges, missed webhooks, idempotency leaks and I write code that prevents them, not code that just works on the happy path.
Before you order: send me your stack, payment provider, and what you need. I'll tell you honestly if I can help.

Backends that touch money have one job: don't surprise anyone — and that's what I've spent the last 9 years making sure of.
Senior Node.js engineer, currently Tech Lead at NovaPay (fintech). I help teams fix fragile payment logic, slow APIs, tricky integrations (Stripe, banks, partner APIs), and legacy code nobody wants to touch.
Stack: Node.js, TypeScript, NestJS, PostgreSQL, Vue.js, Docker.
100% Job Success, $100K+ earned, 27 projects delivered. Tell me what's hurting — I'll be honest if I can help.

FAQ
Do I need a Stripe / PayPal account already?
Yes — you'll need an active account with your chosen provider (Stripe, PayPal, Braintree, etc.). I'll guide you through setup if needed, but the account stays in your name — you're the merchant on record.
Can you integrate into my existing Node.js project, or do I need to start over?
I work directly inside your existing codebase — Express, NestJS, Next.js API routes, or custom backends. No need to rebuild. Just give me repo access and I'll wire payments in cleanly without breaking what's already working.
Do you handle subscriptions, refunds, and disputes?
One-time payments are included in every tier. Subscriptions (recurring billing), refunds, and dispute handling come with Standard and Premium — or as a separate Gig Extra on top of Basic.
Will I be able to test the integration before going live?
Yes. Every tier includes full sandbox / test-mode setup — test card numbers, mock webhooks, and a clear go-live checklist for switching to production keys when you're ready.
Is the integration PCI-compliant?
I build integrations using Stripe Elements / Checkout / Payment Intents (or the equivalent for other providers) — meaning your server never touches raw card numbers. This keeps your PCI scope at the lowest level (SAQ-A). You stay compliant by design, not by promise.
What if I find a bug after delivery?
Each tier includes free revisions for anything that doesn't match the agreed scope. If you need new features or expanded scope after delivery, we agree on a fair price for the additional work — usually as a small follow-up order.
What do you need from me to start?
Three things: (1) your stack and repo access, (2) which payment provider you're using, (3) a quick description of the payment flows you need — one-time? subscriptions? marketplace splits? international cards? That's enough for me to confirm scope and get started same day.
