You will get a production-ready Stripe billing & subscription integration in NestJS


Project details
Billing is where "it works on my machine" gets expensive. A missed webhook or a badly handled failed payment means lost revenue and frustrated customers — so this is exactly the kind of work you want built right the first time.
I'm a Principal Software Engineer with 9+ years building backend systems, and I've delivered billing and payment integrations for companies in fintech and SaaS. You'll get a clean, fully-tested Stripe integration in Node.js / NestJS — not a copy-pasted tutorial, but production-grade code with proper webhook verification, idempotency, and error handling, documented so your team can own it.
I work in Stripe test mode with restricted keys, walk you through everything on handover, and price by scope with no upselling. Not sure which tier fits? Message me and I'll tell you honestly what you actually need.

About Gonzalo
Senior Software Engineer | NestJS, Node.js & AWS Serverless APIs
Buenos Aires, Argentina - 7:40 am local time
I'm a Principal Software Engineer at DEPT® with 9 years of experience, working with clients like SimpliSafe and Moody's on billing integrations, financial platforms, and distributed systems. I care about the same things you do: reliable delivery, maintainable code, and no nasty surprises after launch.
What I can do for you:
REST APIs and microservices in NestJS / Node.js, served on AWS Lambda (Serverless Framework, Step Functions, SNS/SQS)
Billing & subscription integrations — Stripe, Zuora — connecting your app to a reliable source of truth for finance and revenue
Backend architecture done right: DDD, TDD, and Design Patterns so the codebase stays clean as it grows
CI/CD pipelines and infrastructure as code with Terraform, so deployments are boring and repeatable
Full test coverage — I ship code that's verified, not hoped-for
I also work with Claude Code and modern AI tooling to move faster without trading away quality, which means shorter timelines for you.
Whether it's a single API, a billing integration, or a backend service built from scratch, I deliver production-ready work end to end. Check out my Project Catalog below for fixed-scope packages, or message me to talk through what you need.

Kickoff & scope confirmation
A short call to confirm your pricing model, edge cases, and success criteria before any work begins.
Build in Stripe test mode
I develop against test mode with restricted keys — never your live credentials — so you can verify safely at each stage.
