Node.js API Development That Ships Fast
Our senior engineers build production-ready APIs in weeks, not months.
We use Node.js with Express or Fastify to build lightweight, high-throughput APIs. With async architecture, our APIs handle 10,000+ requests per second on a single instance.
Every API includes automated testing with Jest, continuous integration via GitHub Actions, and deployment to AWS or GCP. We deliver full documentation with Postman collections and OpenAPI specs.
Why Choose IRPR for Node.js API Development
Most dev shops deliver slow, insecure APIs. We deliver production-grade APIs on time and on budget.
Generic development shops often start with hourly rates and unclear scope. They assign junior developers and ship APIs without documentation or security audits.
IRPR starts with a fixed price and detailed roadmap. Every API is built by senior engineers, tested for performance and security, and fully documented before deployment.
- Starts with hourly rates and no fixed scope
- Uses junior developers with little Node.js experience
