We build production-grade Node.js APIs for startups and enterprises. 200+ products shipped, fixed pricing from $80K, 8-12 week delivery.
IRPR is a software development studio that provides senior Node.js API development consultants. We build RESTful and GraphQL APIs using Node.js, Express, Fastify, PostgreSQL, MongoDB, Redis, and cloud services like AWS Lambda and Google Cloud Run.
Every engagement ships a production-ready API with CI/CD, monitoring, and documentation. Timelines range from 8 to 12 weeks for an MVP. Pricing is fixed from $80K to $250K. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA standards.
We work with CTOs who need to scale their backend, product managers launching new features, and founders building their first SaaS product. Each client gets a dedicated senior consultant who writes code, reviews architecture, and ships weekly.

Why Hire Senior Node.js API Development Consultants
Building a Node.js API that scales requires experience beyond tutorial-level code.
IRPR's senior Node.js API development consultants have shipped over 200 products across 50 countries. We use Node.js 20, TypeScript, PostgreSQL 16, Redis 7, and deploy on AWS ECS or Google Kubernetes Engine. Every API includes structured logging with Winston, error tracking with Sentry, and uptime monitoring with Datadog.
We write code that handles 10,000+ requests per second with less than 200ms latency. Our APIs are designed for horizontal scaling using load balancers and auto-scaling groups. We also implement caching strategies with Redis to reduce database load by 60%.
The Difference Between IRPR and a Generic Dev Shop
Not all Node.js consultants deliver the same quality. Here is how we compare.
Generic dev shops often assign junior developers to your project. They use boilerplate code, skip testing, and deliver APIs that break under load. You pay hourly and the timeline slips.
IRPR assigns a senior Node.js API development consultant who owns the architecture end to end. We write unit tests, integration tests, and load tests. Every API is documented with OpenAPI and deployed with CI/CD. You get a fixed price and a clear timeline.
- Junior developers with 1-2 years of Node.js experience
- No automated testing, manual QA only
- Hourly billing with no cap
- Timeline slips by 4-8 weeks
- No monitoring or error tracking
- You own nothing, code is kept by the shop
- Senior consultants with 8+ years of Node.js experience
- 90%+ code coverage with Jest and Supertest
- Fixed price from $80K to $250K
- 8-12 week delivery, on time 98% of projects
- Sentry error tracking, Datadog monitoring, PagerDuty alerts
- Full code ownership in your GitHub repo
Our Process for Building Your Node.js API
We follow a four-phase process to deliver your API on time and on budget.
Every project starts with an Idea phase where we map your requirements. Then we move to Roadmap where we define the API endpoints, data models, and deployment plan. The Product phase is where we build and test. Finally, Release deploys to production with monitoring.
We deliver a working API every two weeks. You see the code, test the endpoints, and give feedback. No surprises at the end.
What Ships When You Hire a Senior Node.js API Consultant
Every engagement includes these deliverables by default. No hidden fees.
From day one, you get a private GitHub repository with the source code. We set up CI/CD with GitHub Actions, deploy to AWS or GCP, and configure Sentry for error tracking. You can see the code and infrastructure as it is built.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Deployed to AWS ECS or Google Cloud Run
- Sentry error tracking and Datadog monitoring
- OpenAPI 3.0 documentation
- Postman collection for testing
- Database schema and migration scripts
- Unit tests with Jest (90%+ coverage)
- Integration tests with Supertest
- Load test report with k6

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
We do not hire juniors. Every consultant has 8+ years of Node.js experience and has shipped at least 10 production APIs. You get a senior engineer from day one.
Production-ready from day one
We ship with CI/CD, monitoring, error tracking, and documentation. Your API is ready for production at the end of the engagement. No handoff to another team.
Full code ownership
You own all source code, infrastructure configs, and documentation. We put everything in your GitHub repository. No licensing fees, no vendor lock-in.
Compliance built in
We build APIs that comply with HIPAA, PCI-DSS, SOC 2, and FERPA. We use encryption at rest and in transit, audit logs, and role-based access control.
98% on-time delivery
We track every sprint with Jira and report weekly. Out of 200+ projects, 98% shipped on time. If we are late, we tell you in week 1, not week 10.
