Top Node.js API Development ConsultantsAPI Development
We build production-grade APIs in Node.js with fixed pricing and senior engineers. Over 200 products shipped across 50+ countries.
IRPR builds high-performance Node.js API solutions using Express.js, Fastify, and NestJS. We deliver RESTful and GraphQL APIs with OpenAPI documentation and automated testing.
Every API project ships within 8-12 weeks with fixed pricing from $80K to $250K. Our APIs are built with CI/CD, rate limiting, and monitoring for production readiness.
We work with CTOs needing scalable backends, product managers launching SaaS platforms, and startup founders building MVPs that require robust API infrastructure.
Types of software we ship.
REST API Development
Build RESTful web services with Express.js, JWT authentication, and PostgreSQL. Standard endpoints for CRUD operations.
GraphQL API Development
Schema-first APIs using Apollo Server, Prisma, and code generation. Efficient data fetching for modern frontends.
Real-Time API Development
WebSocket and Socket.io APIs for live chat, notifications, and collaboration. Low-latency event-driven architecture.
Microservices API Development
Event-driven services with Node.js, Kafka, and Docker. Decoupled systems that scale independently.
Third-Party API Integration
Connect to Stripe, Salesforce, HubSpot, and custom APIs. Secure OAuth 2.0 flows and data synchronization.
API Gateway Development
Custom gateways with rate limiting, caching, and authentication. Centralized management for multiple backend services.
Serverless API Development
AWS Lambda and API Gateway functions with Node.js. Pay-per-use scaling for unpredictable traffic patterns.
API Security & Authentication
Implement OAuth 2.0, SAML, or custom JWT. Encryption, audit logging, and compliance with HIPAA or PCI-DSS.
We build for every business type.

Node.js API development with proven metrics
Our track record speaks for itself: every API ships on time and within budget.
We have delivered over 200 products across 50+ countries, with a 98% on-time delivery rate. Our APIs handle millions of requests per day with 99.9% uptime.
Each project starts with a Roadmap phase that defines the scope, timeline, and fixed price. No surprises, no scope creep.
Generic dev shops vs. IRPR: the API development difference
Most dev shops use junior talent and bill by the hour. We do the opposite.
Generic agencies assign junior developers who learn on your project. They use hourly billing that inflates costs, provide minimal documentation, and disappear after launch.
IRPR assigns senior engineers with 10+ years of experience. We work on fixed price, deliver full API documentation, and provide post-launch support with monitoring.
- Junior developers
- Hourly billing
- No documentation
- No CI/CD
- No monitoring
- Scope creep
- Senior engineers only
- Fixed price
- OpenAPI docs
- CI/CD pipelines
- Sentry monitoring
- Clear scope
How we build your Node.js API in 4 phases
Our 4-phase process moves from idea to production in 8-12 weeks.
We follow a four-phase process that guarantees clarity and delivery speed. Each phase has clear deliverables and sign-off points.
What ships with every Node.js API project
Every project delivers production-ready assets, not just code.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification documentation
- CI/CD pipeline with GitHub Actions
- Rate limiting and request validation
- Error tracking with Sentry
- Unit and integration tests
- Docker compose for local development
- API health check endpoints
- Postman collection for testing
- Deployment guide and runbook
What we ship in this practice.
Real-time chat API for a social app
Built a WebSocket API using Socket.io and Redis that scaled to 10,000 concurrent connections. Reduced message latency from 500ms to 50ms.
Payment processing API for a fintech startup
Developed a RESTful API with Stripe integration and PCI-DSS compliance. Handled 50,000 transactions per day with 99.99% uptime.
Patient data API for a telemedicine platform
Created a FHIR-compliant API using Node.js and AWS Lambda. Enabled seamless EHR integration across 200 clinics.
Product catalog API for an e-commerce brand
Built a GraphQL API with Apollo Server and Elasticsearch. Reduced product search response time by 60%.
IoT device management API for a smart building startup
Developed a REST API with MQTT bridge for real-time sensor data. Managed 5,000 devices with 99.9% uptime.
Content management API for a media platform
Built a headless CMS API using Node.js and Contentful. Enabled multi-language content delivery with 2-second cache invalidation.
Why teams hire us.
Fixed price, not hourly
Every API project starts with a Roadmap that locks in the scope and price. You pay one fixed fee for the entire build, no surprise invoices.
Senior engineers only
All IRPR developers have at least 10 years of experience. No juniors, no outsourcing, no learning on your dime.
Full documentation delivered
We ship OpenAPI 3.0 specs, Postman collections, and deployment guides with every API. Your team can integrate and maintain the code immediately.
Production-ready from day one
We include CI/CD, error tracking (Sentry), and uptime monitoring (99.9% SLA). Your API is ready for production traffic the day we deploy.
Post-launch support included
Every project includes 30 days of post-launch support with bug fixes and monitoring. We don't disappear after launch.
Real-world compliance experience
We have built APIs for HIPAA, PCI-DSS, and SOC 2 environments. We know what auditors look for and bake compliance into the architecture.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
