Leading Node.js API Development DevelopersAPI Development
We build production-grade Node.js APIs that scale to millions of requests. 200+ products shipped, 8-12 week delivery, fixed pricing.
IRPR is a software development studio that builds Node.js APIs for startups and enterprises. We use Express, Fastify, and NestJS on the backend, with PostgreSQL, Redis, and MongoDB for data. Every API is designed for horizontal scaling from day one.
We ship a production-ready Node.js API in 8-12 weeks. Pricing is fixed, starting at $80K for a standard REST API and going up to $250K for high-throughput systems with real-time features. We handle compliance like HIPAA, PCI-DSS, and SOC 2.
We work with CTOs who need a scalable backend without hiring a full team. Product managers who want to ship an MVP in 2 months. And founders who need a reliable API to power their mobile app or SaaS product.
Types of software we ship.
REST API development
Build a RESTful API with Express or Fastify. We include OpenAPI docs, rate limiting, and JWT auth.
GraphQL API development
Build a GraphQL API using Apollo Server or Yoga. We integrate with PostgreSQL, MongoDB, and external REST sources.

Why you need leading Node.js API development developers
A poorly built API costs you time, money, and customers. Here is what IRPR delivers.
We have shipped over 200 products across 50 countries. Every API we build is designed for 99.9% uptime and sub-100ms response times. We use Node.js with TypeScript, PostgreSQL, and Redis as our default stack.
Our team consists of senior engineers only. We do not outsource or use junior devs. Every API is reviewed in code reviews, tested with Jest, and deployed via GitHub Actions with automated rollbacks.
Generic dev shops vs IRPR
Most agencies treat your API as a side project. We treat it as the core of your product.
Generic shops often use outdated patterns, skip testing, and hand you code that breaks under load. They charge hourly and have no incentive to finish fast.
IRPR gives you a fixed price, a dedicated senior engineer, and a production-grade API in 8-12 weeks. We own the outcome, not the hours.
- Hourly billing with no cap
- Junior or offshore developers
- No automated testing
- No CI/CD pipeline
- No monitoring or alerts
- Code ownership unclear
- Fixed price from day one
- Senior engineers only (US time zones)
- 100% test coverage on critical paths
- GitHub Actions CI/CD with auto-deploy
- Sentry error tracking and Datadog monitoring
- Full source code ownership
Our Node.js API development process
We follow a proven 4-phase process to ship your API on time and on budget.
Phase 1: Idea. We map your requirements into a technical specification. We identify integrations, data models, and performance targets.
Phase 2: Roadmap. We produce a fixed-price proposal with a detailed timeline. You get a week-by-week plan and a list of deliverables.
What ships with every Node.js API
Every project comes with a full production setup, not just code.
You get a complete, deployable API with documentation, tests, and monitoring. No hidden setup costs.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated tests with Jest and Supertest
- API documentation with OpenAPI/Swagger
- Docker setup for local and production
- Sentry error tracking
- Datadog or Grafana monitoring
- Rate limiting and JWT auth
- Database migrations with Prisma or TypeORM
- Post-launch support for 30 days
What we ship in this practice.
Real-time chat API for a telehealth platform
Built a WebSocket API with Socket.IO and Node.js that handles 10,000 concurrent connections. Reduced message latency to under 50ms. Tech stack: Node.js, Socket.IO, Redis, PostgreSQL.
Payment processing API for a fintech startup
Built a PCI-DSS compliant REST API that processes 5,000 transactions per minute. Integrated with Stripe and Plaid. Tech stack: Node.js, Express, PostgreSQL, Stripe API.
Product catalog API for an ecommerce brand
Built a GraphQL API that serves product data to a React storefront. Reduced page load time by 60%. Tech stack: Node.js, Apollo Server, MongoDB, Redis.
Analytics API for a SaaS dashboard
Built a REST API that aggregates data from 10 sources into a single endpoint. Handles 1 million requests per day. Tech stack: Node.js, Express, PostgreSQL, Redis.
Property listing API for a real estate platform
Built a REST API that integrates with MLS data and serves property listings to a mobile app. Reduced data sync time from 2 hours to 5 minutes. Tech stack: Node.js, Express, PostgreSQL, Elasticsearch.
Course delivery API for an edtech platform
Built a REST API that manages course content, user progress, and quiz results. Supports 50,000 concurrent users. Tech stack: Node.js, NestJS, PostgreSQL, Redis.
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 code.
Senior engineers only
We hire senior Node.js engineers with 5+ years of experience. No juniors, no offshore teams. Every engineer has built and scaled production APIs.
8-12 week delivery
We ship a production-grade API in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects ship on time.
Full code ownership
You own all source code, documentation, and infrastructure config. No licenses, no lock-in. You can take the code to any team after we finish.
Built for scale
We design every API to handle 10x your expected load. We use caching, connection pooling, and horizontal scaling patterns from day one.
Post-launch support included
Every project includes 30 days of post-launch support. We fix bugs, monitor performance, and help your team take over. No handoff surprises.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
