You will get A secure Stripe subscriptions system with webhooks and portal
Project details
You will get a production-ready Stripe subscription billing module that is secure, testable, and easy to integrate into your SaaS backend. I implement the full flow, including Checkout, Customer Portal, webhook signature verification, idempotent event handling, and database synchronization for subscription status. This means your app can reliably grant or revoke access based on real billing state, even when Stripe retries webhook events.
What sets my project apart is engineering quality and delivery clarity: structured APIs, clean TypeScript code, Postgres models, documentation, and practical testing(including Stripe CLI event verification). I also provide a frontend demo flow for subscription, success/cancel redirects, and account billing checks, so you can clearly validate everything before launch.
You will receive maintainable source code, setup instructions, and a workflow your team can extend for upgrades like seat billing, usage-based billing, or advanced lifecycle rules. The result is not just a quick integration, but a dependable billing foundation designed for real production behavior.

+$60About Ankh-Erdene
Node.js Developer | OpenAI API, AI Features, Backend Integrations
Taichung, Taiwan - 7:07 pm local time
My work includes OpenAI-powered features, REST APIs, Stripe billing flows, webhook handling, PostgreSQL-backed services, and backend integrations that need to work reliably in real environments.
I have 5+ years of backend engineering experience across telecom, enterprise systems, payment integrations, and AI-enabled applications. I focus on clean architecture, practical delivery, and systems that are maintainable after launch.
I can help with:
• OpenAI API integrations inside existing products
• Backend APIs using Node.js, TypeScript, PostgreSQL, and Supabase
• Stripe subscriptions, billing logic, and webhook flows
• AI document chat / RAG features with vector search
• Business workflow integrations and backend automation
If you need a backend engineer who can implement reliably and communicate clearly, I’d be glad to help.
