I will build or fix your backend API

Your API is the backbone of your product. I'll make it reliable, fast, and ready for production.

I'm a senior software engineer with 10+ years building and scaling backend systems for fintech, B2B SaaS, and ecommerce products. I've shipped APIs that handle real money (Stripe webhooks), high traffic (~1M SMS/day), and complex business workflows and I know what breaks when you move from prototype to production.

What I can help with:

• Design and build REST APIs from scratch (Rails, Node.js, FastAPI)
• Fix bugs, refactor legacy code, and modernize outdated backends
• Integrate third-party services: Stripe, Algolia, NetSuite, external APIs
• Add background jobs, event-driven workflows, and webhook handlers
• Set up authentication, authorization, and secure data handling
• Write unit and integration tests (RSpec, pytest, Jest)
• Deploy to AWS with CI/CD pipelines

Why work with me:

• I own delivery end-to-end from requirements to release
• Clear communication, async-friendly, remote-first
• I ask the right questions before writing code
• Production-minded: logging, error handling, and test coverage included

Message me before ordering so I can confirm scope and recommend the right package.
