Experienced Node.js API Development FirmDevelopment Firm
We build production-grade Node.js APIs for web and mobile. Senior engineers, 8-12 weeks, fixed pricing.
IRPR is an experienced Node.js API development firm with 200+ products shipped to 50+ countries. We build REST, GraphQL, and WebSocket APIs using Express.js, Fastify, Apollo Server, and tRPC. Our Node.js APIs power fintech platforms, healthcare systems, and SaaS products.
Every project ships in 8-12 weeks with a fixed price determined during the Roadmap phase. Typical Node.js API development projects range from $80K to $250K. We comply with HIPAA, PCI-DSS, SOC 2, and GDPR requirements out of the box.
Founders, CTOs, and product managers hire IRPR when they need a reliable Node.js API that handles thousands of requests per second. Chief architects choose us when their internal team lacks bandwidth for a complex microservices migration.
Types of software we ship.
REST API Development
Build stateless, cacheable REST APIs with Express.js and OpenAPI specs. Includes rate limiting, authentication (JWT/OAuth2), and PostgreSQL or MongoDB.
GraphQL API Development
Schema-first GraphQL APIs using Apollo Server or Yoga. Resolvers connect to multiple data sources with DataLoader batching and real-time subscriptions.
Microservices API Architecture
Decompose monoliths into Node.js microservices with message queues (RabbitMQ, Kafka) and API gateways (Kong, Traefik). Each service is independently deployable.
Real-Time API with WebSockets
Low-latency WebSocket APIs using Socket.IO or ws. Ideal for chat apps, live dashboards, and collaborative tools with Redis pub/sub.
Third-Party API Integration
Connect your Node.js backend to Stripe, Salesforce, HubSpot, Twilio, and 50+ other APIs. Built-in retry logic and webhook handling.
Serverless API Development
Deploy Node.js APIs on AWS Lambda, Google Cloud Functions, or Vercel Edge Functions. Cold starts mitigated with provisioned concurrency.
API Gateway & Proxy Services
Implement a single entry point for multiple backend services. Handle authentication, rate limiting, logging, and request transformation with Express Gateway or custom proxy.
API Security & Compliance Audit
Penetration test your Node.js APIs. Add OWASP protections, input validation (Joi/Zod), encryption (TLS 1.3), and meet PCI-DSS or HIPAA requirements.
We build for every business type.
Fintech & Banking
Healthcare & MedTech
Ecommerce & Marketplaces
SaaS & Enterprise
Logistics & Real-Time Tracking
Why Your Business Needs an Experienced Node.js API Development Firm
A well-architected Node.js API is the backbone of modern web and mobile applications.
Generic development shops often deliver APIs that break under load or fail to scale. IRPR's senior engineers have built APIs handling over 50,000 requests per second for fintech clients. We use PM2 clustering, Redis caching, and horizontal scaling on AWS ECS.
Every API we build includes automated CI/CD with GitHub Actions, Sentry error tracking, and Datadog monitoring. Our 98% on-time delivery rate means you launch on schedule. We have shipped 200+ products across 50+ countries.
What Sets IRPR Apart as an Experienced Node.js API Development Firm
Most agencies promise quality but deliver chaos. We deliver a predictable process and production-grade code.
We do not use offshore random developers. Every engineer at IRPR has 8+ years of experience and works from the US, UK, and EU time zones. Our Roadmap phase (week 2) produces a fixed price contract and a detailed technical specification.
You own 100% of the source code, infrastructure configs, and documentation. No license fees, no vendor lock-in. We use your AWS or GitHub account from day one.
- Hourly billing that inflates scope
- Junior developers learning on your project
- No uptime SLA or monitoring
- API breaks under load - no load testing
- Proprietary code you cannot take
- No compliance (HIPAA/PCI) knowledge
- Fixed price from Roadmap phase (week 2)
- Senior Node.js engineers only (8+ years)
- 99.9% uptime SLA with Datadog monitoring
- Load testing with Artillery up to 100K RPS
- Full source code in your GitHub repo
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
Our Process for Building Your Node.js API
From idea to production in 8-12 weeks with a fixed budget.
We follow a four-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go decision point. No open-ended sprints.
During Roadmap (week 1-2) we produce a detailed API specification, database schema, infrastructure diagram, and a fixed price contract. Product phase (weeks 3-10) is continuous delivery with daily builds.
What Ships When You Hire IRPR
Every project includes these deliverables by default. No additional charges.
You own everything - the code, the docs, the infrastructure. We use your accounts (GitHub, AWS, Stripe) from day one. Nothing is hidden behind IRPR's licenses.
Our checklist ensures your Node.js API is production-ready on launch day. We do not hand over half-finished work.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error tracking integrated
- Datadog monitoring dashboard (API latency, error rate, RPS)
- OpenAPI / Swagger documentation generated automatically
- Docker Compose setup for local development
- Load test report (Artillery with 10K concurrent users)
- Deployment guide for AWS ECS or Lambda
- Postman collection for all endpoints
- 30-day post-launch support and bug fixes
What we ship in this practice.

Why teams hire us.
Fixed Price, Not Hourly Billing
Every project receives a fixed price quote after the Roadmap phase (week 2). No hourly billing means no surprise invoices. You know the exact cost before engineering begins.
Senior Engineers Only, No Juniors
Every developer at IRPR has 8+ years of Node.js experience. We do not outsource to junior teams. Your API is built by engineers who have shipped production systems handling 50K+ requests per second.
Production-Grade From Day One
We ship CI/CD, monitoring (Datadog), error tracking (Sentry), and load testing (Artillery) as standard. Your Node.js API goes to production with 99.9% uptime SLA and observability built in.
Full Code Ownership
You own 100% of the source code, infrastructure configs, and documentation. We work in your GitHub and AWS accounts. No proprietary frameworks or vendor lock-in.
Built-In Compliance (HIPAA, PCI-DSS, SOC 2)
Our Node.js APIs are designed for regulated industries from the start. We include encryption, audit logging, data segregation, and compliance documentation. No costly retrofits.
8-12 Week MVP Delivery
From kickoff to production launch in 8-12 weeks. Our framework (Idea-Roadmap-Product-Release) keeps every sprint focused. 98% of our projects ship on time.
