Why IRPR is a Top Node.js API Development Company
We deliver production-grade Node.js APIs on time and on budget.
IRPR has shipped 200+ products across 50+ countries. Our Node.js APIs handle millions of requests per day with 99.9% uptime. We use Express, NestJS, and Fastify with PostgreSQL, MongoDB, and Redis.
Every API includes automated testing with Jest, CI/CD via GitHub Actions, and monitoring with Sentry and Datadog. We deploy on AWS, GCP, or Azure using Docker and Kubernetes.
The IRPR Difference for Node.js API Development
We don't just code. We architect, test, and ship production-ready APIs.
Most development shops deliver incomplete APIs with no tests, no docs, and no deployment scripts. IRPR ships a complete API with documentation, test coverage, and a CI/CD pipeline.
We use a fixed-price model. After a 2-week Roadmap phase, you know exactly what you get and what it costs. No hourly billing, no scope creep.
- Hourly billing with unclear scope
- No automated tests
- No API documentation
- No CI/CD pipeline
- No monitoring or error tracking
- Delayed delivery by months
- Fixed price from the Roadmap phase
- 90%+ test coverage with Jest
- OpenAPI/Swagger docs auto-generated
- CI/CD on GitHub Actions or GitLab
- Sentry + Datadog monitoring
- 8-12 week delivery guaranteed
How We Build Your Node.js API
A proven 4-phase process from idea to deployment.
We start with a 2-week Roadmap phase where we define the API contract, database schema, and tech stack. Then we build the MVP in 6-10 weeks with bi-weekly demos.
After launch, we provide 30 days of hyper-care support and hand over full source code. You own everything.
What Ships with Every Node.js API
You get a production-ready system, not just code.
Every API includes everything needed to run in production. No hidden dependencies, no missing pieces.
- Source code in your private GitHub/GitLab repo
- OpenAPI 3.0 specification (Swagger UI)
- Automated test suite with Jest (90%+ coverage)
- CI/CD pipeline on GitHub Actions
- Docker containers for local and production
- Sentry error tracking and performance monitoring
- Datadog or CloudWatch dashboards
- Deployment scripts for AWS, GCP, or Azure
- Postman collection for manual testing
- README with setup instructions and architecture diagram

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Our team has 10+ years average experience. We don't outsource or use junior developers. Every engineer has shipped at least 5 production Node.js APIs.
8-12 week delivery
We ship MVPs in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects deliver on time.
Full ownership of code
You own all source code, documentation, and infrastructure. No licensing fees, no vendor lock-in. We hand over everything at the end of the project.
Built-in compliance
We build APIs that meet HIPAA, PCI-DSS, SOC 2, and FERPA requirements. Our engineers implement encryption, access controls, and audit logs by default.
Production-ready from day one
Every API ships with automated tests, CI/CD, monitoring, and documentation. You can deploy to production on day 1 of the handoff.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
