I will integrate stripe payments, webhooks and subscriptions in your app
Yaroslav T.
About this gig
Stripe integration done right webhooks, idempotency, subscriptions, and refunds that actually work.
Most Stripe integrations break in production. Webhooks miss events. Duplicate charges go through. Subscriptions cancel silently. I fix that.
I'm a full-stack developer with 3.5+ years building production payment systems. I integrate Stripe and PayPal into Node.js, Next.js, and React apps properly, the first time.
What I deliver:
- Stripe Checkout, Payment Element, or custom card flow
- Webhooks with idempotency and signature verification
- Subscriptions and Customer Portal setup
- Refunds, partial refunds, and dispute handling
- Stripe Connect for marketplaces and multi-vendor payouts
- Apple Pay, Google Pay, SCA / 3D Secure compliance
- Documented code with tests on critical paths
Stacks: Node.js, Next.js, Express, TypeScript, React, PostgreSQL, MongoDB, Supabase, Prisma.
Why message me first: every project is different. Send your repo or short description and I will reply within a few hours with a clear plan, fixed price, and timeline. No templates, no scope creep, no missed deadlines.

FAQ
What if my codebase is messy or uses an unusual stack?
That is fine. I can work with existing Node.js, Next.js, Express, Python, or PHP projects, even legacy ones. Before starting, send me your repo or a short description and I will tell you exactly what is doable and what needs cleanup first. Honest scope from day one — no surprises later.
How do you handle webhooks and idempotency?
Every Stripe integration I build verifies webhook signatures, uses idempotency keys on retries, and stores event IDs to prevent duplicate processing. This is the part most freelancers skip — and the reason production integrations break silently months later.
Can you integrate Stripe Connect for a marketplace?
Yes. Stripe Connect with multi-vendor payouts, platform fees, and onboarding flows is part of the Premium package. Whether you are building a marketplace, SaaS with reseller logic, or a multi-tenant platform — message me with your model and I will scope it.
Do you also work with PayPal or other payment gateways?
Yes. PayPal Checkout, Braintree, and most major gateways are fine. If your project needs both Stripe and PayPal in the same checkout flow, I handle the routing, fallback logic, and unified webhook handling so you do not end up with two broken systems.
Will my Stripe API keys and secrets stay safe?
Always. I never commit secrets to git, never share them outside our conversation, and recommend secret managers like Vercel env vars, AWS Secrets Manager, or Doppler. I can also rotate keys after delivery if you want zero residual access on my end.
What do you need from me to start?
Access to your repo (or a short technical description if no repo yet), your Stripe account in test mode, and a clear description of the payment flow you need. If you are unsure about anything, just message me first — I will guide you through what is required.
Do you write tests and provide documentation?
For Standard and Premium packages, yes — tests cover critical payment paths and edge cases (failed payments, expired cards, webhook retries), and you get a short README explaining the integration. For Basic, I provide inline code comments and a clear setup guide.
