Premium Node.js API Development CompanyNode.js API
We build production-grade Node.js APIs for startups and enterprises. Ship your MVP in 8-12 weeks with a fixed price.
IRPR builds premium Node.js APIs for web apps, mobile backends, and microservices. We use Express.js, Fastify, GraphQL, and TypeScript to deliver scalable endpoints.
Most MVPs ship in 8-12 weeks. Fixed pricing starts at $80K and goes to $250K. All APIs include SOC 2 compliance documentation and automated testing.
Startups launching a SaaS product need a reliable backend. Enterprises migrating legacy APIs to Node.js hire us. CTOs of healthcare and fintech companies require HIPAA or PCI-DSS compliant APIs.
Types of software we ship.
RESTful API Development
Build REST APIs with Express.js or Fastify. Includes versioning, pagination, rate limiting, and Swagger docs.
GraphQL API Development
Create GraphQL APIs using Apollo Server or Yoga. Stitch schemas, add subscriptions, and optimize with DataLoader.
Microservices Architecture
Decompose monoliths into independent Node.js services. Use RabbitMQ, Kafka, or NATS for inter-service communication.
Real-Time API (WebSocket)
Implement real-time endpoints with Socket.IO or WebSocket. Ideal for chat, live dashboards, and collaboration tools.
Third-Party API Integration
Connect your app to Stripe, Salesforce, Twilio, Slack, and 50+ other APIs. All integrations included in the fixed price.
API Gateway & Management
Set up a central gateway with Kong or Express Gateway. Add caching, authentication, and usage analytics.
Serverless API
Deploy Node.js APIs on AWS Lambda, Vercel, or Netlify. Auto-scale with zero cold starts using provisioned concurrency.
API Documentation & SDKs
Generate OpenAPI 3.0 specs from code and auto-create client SDKs for JavaScript, Python, and mobile.
We build for every business type.

Premier Node.js API Development at Scale
Our APIs power 200+ products across 50+ countries, with 99.9% uptime and 12-week delivery.
IRPR builds APIs that handle millions of requests per day. We use TypeScript from the start, giving you type safety and better refactoring. Every endpoint is tested with 95% code coverage.
Our team of senior Node.js engineers has deep experience with PostgreSQL, Redis, and AWS Lambda. We ship with CI/CD pipelines, Datadog monitoring, and auto-generated API docs.
Why generic dev shops fail and IRPR delivers
Most agencies deliver fragile APIs that break at scale. IRPR builds production-grade APIs from day one.
We see projects where the API has no TypeScript, no tests, and no monitoring. The client inherits a black box that crashes under load. That does not happen with IRPR.
Every API we ship includes TypeScript, automated tests, CI/CD, and observability. You get a documented, scalable system that your team can extend immediately.
- No TypeScript
- Poor test coverage
- No CI/CD
- No monitoring
- Hourly billing
- No documentation
- TypeScript from the start
- 95%+ test coverage
- CI/CD with GitHub Actions
- Datadog monitoring
- Fixed price
- Auto-generated OpenAPI docs
How we build your Node.js API in 4 phases
Our process from idea to production takes 8-12 weeks, with fixed scope and price.
Each phase has clear deliverables. You see progress every week and approve decisions before we move forward. No surprises, no scope creep.
We pair program on critical paths and run code reviews on every pull request. Your team gets a production-ready API with full ownership.
What ships with your API
Every project includes these deliverables as standard.
You get everything you need to run and extend the API after launch. No hidden costs, no missing pieces.
Our team uploads the code to your GitHub repository on day one. You own the code from the first commit.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated API tests (unit + integration)
- OpenAPI 3.0 / Swagger documentation
- Dockerized local development setup
- Sentry error tracking
- Datadog monitoring dashboards
- Postman collection for manual testing
- Deployment playbook for your cloud (AWS, GCP, or Azure)
- 1-month post-launch support with priority response
What we ship in this practice.
Real Estate MLS API
Built a unified API for a national real estate platform aggregating MLS data from 200+ sources. Reduced data sync time by 60% using Node.js + Elasticsearch. API handles 500K requests per day with 99.9% uptime.
Fintech Payment Gateway API
Developed a PCI-DSS compliant payment processing API for a startup. Handles 10K+ transactions per minute with 99.99% uptime using Node.js and Stripe Connect. Integrates with Plaid for bank account verification.
SaaS Analytics API

Healthcare Telemedicine API
Built a HIPAA-compliant WebSocket API for real-time video consultations. Integrated with Epic EHR, reducing doctor admin time by 4 hours/day. API logs all access for audit trails.
Ecommerce Product Catalog API
Developed a GraphQL API for a large ecommerce brand. Handles 1M+ product SKUs with sub-50ms response times using Node.js + DynamoDB. Supports faceted search and real-time inventory updates.
Logistics Route Optimization API
Created a microservices API for a logistics startup. Integrated with Google Maps and Weather APIs to optimize delivery routes, cutting fuel costs by 15%. API processes 10K route requests per hour.
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. Our 98% on-time delivery rate proves the model works.
TypeScript-first development
We write all APIs in TypeScript from day one. This gives you compile-time error checking, better IDE support, and easier refactoring. We enforce strict mode and use ESLint with 100+ rules.
Production-grade testing
Our APIs ship with 95%+ code coverage including unit, integration, and load tests. We run tests on every pull request via GitHub Actions. You get a stability guarantee.
Built-in monitoring and observability
Every API includes Datadog dashboards, Sentry error tracking, and structured logging with Winston. We set up alerts for error rates, latency, and traffic spikes. You know the health of your API in real time.
Compliance-ready (SOC 2, HIPAA, PCI)
We build APIs that meet SOC 2, HIPAA, and PCI-DSS requirements. Our team has delivered compliant APIs for healthcare and fintech clients. We document encryption, access controls, and audit trails.
Full code ownership
You own the entire codebase from the first commit. We upload to your GitHub repository and transfer all licenses. No vendor lock-in, no recurring fees. Your team can take over immediately.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
