Experienced Node.js API Development CompanyAPI Development
We build production-grade Node.js APIs for SaaS, fintech, and healthcare. Fixed price, 12-week delivery, full ownership.
IRPR is an experienced Node.js API development company that builds REST and GraphQL APIs using Express, Fastify, and NestJS. We deploy on AWS Lambda, Docker, or Kubernetes with automated CI/CD.
Each project ships in 12 weeks for MVPs, with fixed pricing from $80K to $250K. We handle PCI-DSS, HIPAA, SOC 2, and FERPA compliance for every API.
Founders, CTOs, and product managers hire us when they need a production-ready API without hiring in-house. They want predictable costs, senior engineers (no junior staff), and a team that has done it before.
Types of software we ship.

Why You Need an Experienced Node.js API Development Company
A poorly designed API costs you customers, engineers, and security audits.
IRPR has built 200+ products with Node.js APIs. Our senior engineers follow proven patterns: modular routing, request validation with Joi/Zod, centralized error handling, and structured logging with Pino.
We write integration tests with Supertest and Jest, achieving 90%+ coverage on every endpoint. Our CI/CD pipeline runs linting, tests, and security scans before deploying to staging.
How IRPR Compares to Other API Agencies
Most dev shops assign junior engineers and bill hourly. We don't.
IRPR assigns senior Node.js developers with 8+ years of experience. You get a fixed price after the Roadmap phase (week 2), and we never bill by the hour.
We ship incremental value every sprint. By week 12 you have a production-ready API with documentation, monitoring, and deployment scripts.

- hourly billing, no cap
- no compliance expertise
- no automated tests
- handoff without docs
- no post-launch support
- senior Node.js engineers
- fixed price from Roadmap
- HIPAA, PCI, SOC 2, FERPA ready
- 90%+ test coverage
- OpenAPI docs included
- 60-day support after launch
Our Node.js API Development Process
We follow a four-phase framework to ship APIs on time and on budget.
In the Idea phase we audit your requirements and existing architecture. The Roadmap phase (week 2) delivers a detailed spec, estimation, and fixed price contract.
The Product phase runs in 2-week sprints with demos. The Release phase includes production deployment, bug fixes, and documentation handoff.
What Ships with Every Node.js API from IRPR
You own every line of code. No black boxes.
We deliver a complete production-ready API with all assets listed below. Your team can deploy, extend, and maintain the API without IRPR.
All code is stored in your GitHub repository. We configure CI/CD, monitoring, and logging so the API runs reliably from day one.
- Source code in your GitHub repo
- OpenAPI 3.0 specification (Swagger)
- CI/CD pipeline with GitHub Actions
- Postman collection for manual testing
- Sentry error tracking integration
- Structured logs with Pino shipped to your ELK/Prometheus
- Docker Compose for local development
- Deployment scripts for AWS/GCP/Azure
- API authentication (JWT / API keys)
- 60-day post-launch support
