You will get Stripe payments integrated into your React or Next.js app
Project details
Payments are where projects get stuck — I make them just work. I integrate Stripe into your React or Next.js app cleanly and securely: Checkout, subscriptions, webhooks, 3DS, and multi-currency, tested end to end.
6+ years building production web apps, including a platform that processes real Stripe payments (deposits, full-payment, multi-currency) for a brand now at ~$4M in revenue. I know the parts that break — webhook verification, idempotency, failed-payment and refund flows — and I handle them properly.
You get a working payment flow in test and live mode, secure webhooks, clean success/error handling, and clear notes on how it's wired. Your keys stay yours; I use test keys until you're ready to go live.
Send your repo and Stripe details — I'll reply with a clear first step. Need subscriptions or a customer portal? Go with the Checkout + Webhooks or Subscriptions + Portal tier.

About Serdar
Next.js & NestJS Developer - SaaS MVPs with Stripe Billing
Dubai, United Arab Emirates - 1:52 am local time
I've got six years of commercial experience under my belt. Frontend: React, Next.js, TypeScript. Backend when needed: Node.js and NestJS.
🚀 Recent results:
✅ Built a 7-step booking funnel for a travel startup (Next.js, Stripe with 3DS). Offer-to-checkout conversion grew by about 15%.
✅ Set up Playwright E2E tests and an analytics layer (GTM + Amplitude). Critical regressions dropped by about 35%.
✅ Migrated a product from React to Next.js with clean architecture. New features now ship about 30% faster.
🤝 How I work:
💬 Daily updates, short and clear.
📋 Honest estimate before I start. If something changes, you hear it from me first.
🧹 Clean TypeScript code the next developer can read without pain.
🛠️ I take frontend projects (React, Next.js) and full-stack JavaScript projects (React + NestJS): new builds, features in existing products, bug fixes, performance work, REST APIs.
