Expert Node.js API Development ServicesAPI Development
You need a fast, secure, and scalable Node.js API. IRPR builds production-grade APIs in 12 weeks with fixed pricing.
IRPR builds expert Node.js API development services using Node.js, Express, TypeScript, PostgreSQL, Redis, Docker, and Kubernetes. We create REST APIs, GraphQL endpoints, and microservices that handle thousands of requests per second.
Every project ships with source code, CI/CD pipelines, API documentation (Swagger/OpenAPI), Postman collections, and monitoring dashboards. Delivery takes 10-14 weeks with fixed pricing from $80K to $250K. We comply with SOC 2, HIPAA, and PCI-DSS standards.
We are hired by CTOs scaling SaaS platforms who need reliable APIs, fintech startups requiring PCI-compliant payment APIs, healthcare companies building HIPAA-compliant data exchange, and ecommerce brands creating high-performance product APIs.
Types of software we ship.
REST API Development
Build RESTful APIs with Node.js, Express, and PostgreSQL. Supports OAuth 2.0 and rate limiting via Redis.

Why expert Node.js API development services matter
APIs are the backbone of modern software. A poorly built API slows down your product and introduces security risks.
IRPR has built over 200 Node.js APIs for startups and enterprises across 50 countries. We focus on clean architecture, thorough testing, and deployment automation. Every API is designed to handle 10x your current traffic without breaking.
Our expert Node.js API development services include load testing with k6, security audits covering OWASP Top 10, and automated deployment to AWS or GCP. You get a production-ready API with a 99.9% uptime guarantee.
The difference between IRPR and a generic dev shop
Not all Node.js API development services are the same. Here is how IRPR stands apart.
Generic dev shops skip security reviews, skip load testing, and hand you undocumented code. You end up with an API that breaks under traffic and cannot be maintained.
IRPR treats your API like a product. We write automated tests, generate Swagger docs, set up CI/CD, and monitor every endpoint. You get a clean, documented, and resilient API from day one.
- no API security review
- no load testing
- no CI/CD pipeline
- no API documentation
- no uptime SLA
- no monitoring dashboard
- OWASP Top 10 security audit included
- load testing with k6 and Artillery
- CI/CD pipeline with GitHub Actions
- auto-generated Swagger/OpenAPI docs
- 99.9% uptime SLA
- Datadog monitoring and alerts
How we deliver your Node.js API in 12 weeks
We follow a four-phase process to build expert Node.js APIs on time and on budget.
Phase 1 defines the API contract using OpenAPI spec. Phase 2 develops the API with test-driven development. Phase 3 sets up CI/CD and deploys to staging. Phase 4 monitors and optimizes after launch.
Every phase includes a review with your team. We ship working code every two weeks. No surprises, no scope creep.
What ships with every Node.js API
When you hire IRPR for expert Node.js API development services, you get more than just code.
We deliver everything you need to run and maintain your API independently. No black boxes, no hidden dependencies.
Our standard deliverable includes documentation, test suites, deployment scripts, and monitoring tools. You can hand it to any Node.js developer and they can hit the ground running.
- Source code in your Git repository
- CI/CD pipeline on GitHub Actions
- API documentation (Swagger/OpenAPI)
- Postman collection with example requests
- Docker images for every service
- Load test reports from k6 or Artillery
- OWASP Top 10 security audit report
- Datadog dashboard with key metrics
What we ship in this practice.
Fintech Payment API
Built a PCI-compliant payment API for a lending platform using Node.js, TypeScript, and Stripe. Reduced failed transactions by 15% and cut chargebacks by 20%.
Healthcare Data Exchange API
Developed a HIPAA-compliant FHIR API for a telehealth startup. Cut integration time for partner clinics from 6 weeks to 2 weeks using Node.js and AWS Lambda.
Ecommerce Product API
Created a high-performance product search API for a retailer with 10M SKUs. Handles 10,000 req/sec with 50ms latency using Node.js, Redis, and Elasticsearch.
SaaS REST API for CRM
Rebuilt a legacy REST API for a CRM platform using Node.js and GraphQL. Decreased page load by 40% and improved API response times by 60%.
Logistics Tracking API
Built a real-time tracking API for a delivery startup using Node.js, WebSocket, and MongoDB. Improved tracking accuracy to 99.5% and reduced support tickets by 30%.
Real-Time Chat API
Developed a scalable chat API for a collaboration app using Socket.io and Redis. Supported 1 million concurrent users with sub-100ms message delivery.
Why teams hire us.
Fixed price, not hourly
We quote a fixed price during the Roadmap phase (week 2). No hourly billing, no surprise invoices. Our expert Node.js API development services range from $80K to $250K.
Senior engineers only
All IRPR engineers have 10+ years of Node.js experience. We do not outsource or use junior developers. Every API is built by a senior engineer who understands distributed systems.
Security by default
Every API includes an OWASP Top 10 security audit. We use encryption at rest and in transit, enforce rate limiting, and apply automatic dependency scanning. HIPAA and PCI-DSS compliance are built in.
Scalable architecture
We design APIs for scale from the start. Our Node.js APIs are load tested to handle 100,000 requests per second. We use Redis caching, asynchronous message queues, and horizontal scaling.
API documentation included
We ship auto-generated Swagger/OpenAPI documentation and a Postman collection. Your developers can start using the API the day we deploy, without needing to read code.
Post-launch support for 30 days
After deployment, we monitor your API for 30 days using Datadog. We fix any critical issues within 4 hours. You get a smooth handoff and ongoing optional maintenance.
