Node.js API Development FirmAPI Development
We deliver production-grade Node.js APIs in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR is a Node.js API development firm that builds scalable, secure, and production-grade APIs using Node.js, Express, NestJS, and GraphQL. We ship RESTful and event-driven APIs with Swagger documentation, automated testing, and CI/CD pipelines on GitHub Actions.
Every project ships in 8-12 weeks on a fixed price between $80,000 and $250,000. We build to HIPAA, PCI-DSS, and SOC 2 compliance standards, and we include full code ownership, Postman collections, and Docker containerization by default.
We work with CTOs launching SaaS platforms, fintech founders building payment APIs, healthcare product managers needing HIPAA-compliant backends, and ecommerce brands scaling their checkout and inventory systems.
Types of software we ship.
REST API
Standard resource-oriented APIs for CRUD operations. Used with Express.js, MongoDB, and Postman collections.
GraphQL API
Flexible query-based APIs for complex data needs. Built with Apollo Server and integrated with PostgreSQL.
Microservices API
Distributed, independently deployable services communicating via gRPC or message queues. Uses Docker, Kubernetes.
Backend for Mobile App
Tailored APIs for iOS and Android apps. Includes push notifications (Firebase), authentication (Auth0), and offline sync.
Real-Time API
WebSocket and SSE APIs for live data streams. Built with Socket.io, Redis Pub/Sub, and used for chat or live dashboards.
Third-Party Integration API
Custom bridges to external services like Stripe, Twilio, Salesforce, and Slack. Each integration is tested and monitored.
Internal Tool API
Admin dashboards and internal system APIs. Integrated with role-based access control (JWT) and audit logging.
Data Processing API
Batch and streaming APIs for ETL, file upload, and analytics. Uses Bull queues, AWS Lambda, and S3.

Node.js API Development Firm: Metrics That Matter
Every Node.js API we ship is measured against real-world production standards.
IRPR has delivered over 200 Node.js APIs across 50+ countries. Our average project timeline is 12 weeks, and 98% of projects ship on schedule. Each API is built with a fixed price starting at $80,000, with no hourly billing or scope creep.
We maintain 99.9% uptime SLA on all production APIs. Every API comes with automated monitoring (Sentry, Datadog), load testing (k6), and security scanning (Snyk). Our senior engineers average 12 years of experience each.
Generic Dev Shop vs. IRPR: The Real Difference
Not all Node.js API firms are the same. Compare what you get.
Many dev shops start with hourly billing and vague timelines. They often lack compliance experience and may not assign senior engineers to your project. You may end up with code you don't own and no post-launch support.
IRPR works differently. We assign senior Node.js engineers (average 12 years), give you a fixed price in the first 2 weeks, and build to HIPAA, PCI-DSS, and SOC 2 standards. You get full code ownership, 30 days of free support, and async-first communication with daily US overlap.
- Hourly billing with no project cap
- Junor or mixed-senior teams
- No compliance experience
- No fixed delivery date
- You don't own the code explicitly
- No post-launch support
- Fixed price from week 2, no surprises
- Senior Node.js engineers only (avg 12 yr)
- HIPAA, PCI-DSS, SOC 2 built in
- 8-12 week delivery, 98% on time
- You own every line of code
- 30 days free support after launch
Our Node.js API Development Process
We follow a structured 4-phase approach to ship your API in 8-12 weeks.
Every project starts with a 1-2 week discovery phase where we define endpoints, data models, and integrations. We then produce a detailed Roadmap document with fixed price and timeline.
After you approve the Roadmap, our engineers build the API in sprints of 2 weeks each. You get a staging environment with continuous deployment from day 1. We deploy to production only after passing security and load tests.
Everything That Ships with Your Node.js API
Every API comes with these deliverables by default.
When you hire IRPR as your Node.js API development firm, you don't just get endpoints. You get a complete, production-ready system with everything needed to run, maintain, and scale.
All deliverables are documented in your private GitHub repository from day one. We use automated tooling to ensure nothing is missed.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Swagger/OpenAPI specification for every endpoint
- Postman collection for manual testing
- Docker containers for local and production deployment
- Unit and integration tests with 90%+ coverage target
- Security audit report using Snyk and OWASP checks
- Load test results using k6 (500+ concurrent users)
- Deployment runbook and environment variables template
- 30 days of free post-launch support and bug fixes
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a PCI-DSS compliant API that processed $5M in monthly transactions. Used Node.js, Express, Stripe Connect, and Postgres. Reduced transaction failure rate by 35%.
Patient Data API for Telemedicine Platform

Real-Time Inventory API for Ecommerce Brand
Built a WebSocket-based API that syncs inventory across 3 warehouses in real-time. Uses Socket.io, Redis, and Node.js. Reduced overselling incidents by 90%.
Order Fulfillment API for Logistics Company
Developed a microservices API that handles routing, tracking, and delivery confirmation. Integrated with Mapbox and AWS SQS. Processed 50,000+ orders per day with 99.99% uptime.
Content Delivery API for Media Platform

Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Our average project is $80,000-$250,000.
Senior engineers only
Our Node.js engineers average 12 years of experience. You get a Lead Architect and two developers assigned to your project. Every line of code is peer-reviewed before deployment.
Compliance baked in from day 1
We build HIPAA, PCI-DSS, and SOC 2 controls into architecture, not bolted on later. Our APIs include encryption at rest and in transit, audit logging, and role-based access control.
Async-first with US overlap hours
We work across time zones but guarantee at least 4 hours of real-time overlap with your team (typically 9am-1pm EST or PST). You get daily standup updates via Slack or email.
Full code ownership
You own all source code, documentation, and deployment artifacts. There are no licensing fees, no ongoing royalties. Your code is in your GitHub repo from the first commit.
Post-launch support included
Every project includes 30 days of free post-launch support for bug fixes, hotfixes, and documentation updates. After that, we offer flexible maintenance retainers starting at $5,000/month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
