I will integrate third party apis and build a custom node and express backend
Ahmet Emin
About this gig
Your app needs to talk to Stripe, an auth provider or that one API with terrible docs, and a broken integration means lost payments and frustrated users. I build reliable API integrations and backends that just work, with proper error handling and security baked in.
What you get: third-party API integration (payments, CRMs, shipping, AI, anything with an API); Stripe and payment integration (checkout, subscriptions, webhooks, refunds); authentication with Clerk, NextAuth, Auth0 or custom JWT; custom REST or GraphQL API design and development; database design and optimization (PostgreSQL, MongoDB, Supabase); plus validation, security, docs and deployment.
Tech: Node.js, Express, Python, REST, GraphQL, PostgreSQL, MongoDB, Supabase, Stripe, Clerk, NextAuth, Docker and webhooks.
Why me? Integrations fail in the edge cases: expired tokens, failed webhooks, rate limits. I handle those properly so your system doesn't silently break in production. You get clean, documented, secure code your team can maintain.
Tell me which API or system you need connected and I'll confirm feasibility and scope, for free.

FAQ
The API I need has bad or no documentation, can you still integrate it?
Yes, reverse-engineering poorly documented APIs is part of the job. Send me whatever docs or endpoints exist (or the dashboard) and I'll figure out the rest and integrate it cleanly.
Will the payment integration be secure and production-ready?
Absolutely. I implement Stripe (or other gateways) with secure webhooks, proper validation and PCI-friendly practices, never storing card data. You get a payment flow that's safe to launch.
Can you work with my existing codebase?
Yes. I integrate into your current backend or frontend without rewriting it, following your existing patterns. Share your repo (or a sample) and I'll fit in cleanly.
