Expert Node.js API Development AgencyAPI Development
We build production-grade Node.js APIs for startups and enterprises. Ship faster with a senior team that delivers in 8-12 weeks.
IRPR builds scalable, secure Node.js APIs using Express, Fastify, NestJS, PostgreSQL, Redis, Docker, and AWS. Every API gets load testing at 10,000 concurrent requests and achieves sub-50ms p99 latency.
We ship production-ready Node.js APIs with 8-12 week timelines and fixed prices from $80K to $250K. All projects include CI/CD, Sentry error tracking, Swagger documentation, and compliance documentation for HIPAA, PCI-DSS, or SOC 2.
CTOs needing a Node.js API for a SaaS product hire us to cut time-to-market. Founders building mobile app backends choose us for real-time data sync. Enterprises migrating from monolithic APIs use us for microservices decomposition. Healthcare companies engage us for HIPAA-compliant FHIR APIs.
Types of software we ship.
REST API Development
Stateless JSON APIs for CRUD operations. We build with Express or Fastify and auto-generate OpenAPI specs. Integrates with Stripe, Twilio, SendGrid.
GraphQL API Development
Typed query languages with Apollo Server or Hasura. Perfect for data-heavy dashboards and mobile clients. Includes GraphQL federation for microservices.
Microservices API Architecture
Decoupled services communicating via gRPC or message queues. We use Docker, Kubernetes, and RabbitMQ to handle 100k+ events per second.
Real-time API (WebSocket)
Bidirectional event-driven APIs with Socket.io or native WebSockets. Used for live chat, collaborative editing, and financial tickers.
API Integration & Middleware
Connect your existing systems with third-party APIs like Salesforce, HubSpot, or QuickBooks. We build middleware with Node.js and handle rate limiting, retries, and caching.
Third-Party API Wrapper
Simplify complex external APIs into clean SDKs. We normalize responses, handle authentication, and add retry logic with exponential backoff.
Internal API for Enterprise
Private APIs for departments like HR, finance, or inventory. Secured with OAuth2, Okta, or Azure AD. All endpoints logged for audit compliance.
Serverless API (AWS Lambda)
Event-driven Node.js APIs on AWS API Gateway + Lambda. Autoscaling from 0 to 10k requests in seconds. Costs start at $0 per idle.
We build for every business type.

The numbers behind our Node.js APIs
Every API we build is measured against real production benchmarks.
Over 200 Node.js APIs shipped to production across 50+ countries. Our average response time stays under 30ms with 99.9% uptime guaranteed in SLAs.
98% of our projects finish on time and on budget. We maintain a 4.9/5 client satisfaction score on independent review platforms.
Generic dev shop vs IRPR
Most API projects fail due to unclear scoping, hourly billing, and junior developers.
We see it all the time: a client hires a generic shop, gets handed off to junior devs, and the API ships with missing endpoints, no documentation, and constant downtime.
IRPR works differently. Senior engineers (average 10+ years experience) own your project from kickoff to release. You get a fixed price, full documentation, and 24/7 monitoring.
- Unclear requirements -> endless revisions
- Hourly billing with no cost ceiling
- Junior developers with no Node.js specialization
- No compliance documentation
- Slow delivery (6+ months for simple API)
- No code ownership guarantee
- Fixed price from week 2 Roadmap
- Senior engineers with 10+ years Node.js
- HIPAA, PCI-DSS, SOC 2 compliance built in
- 8-12 week delivery with weekly demos
- Full code ownership in your repository
- CI/CD, monitoring, and logs included
Our build process for Node.js APIs
Four phases. No surprises.
Every project starts with a 2-week Discovery phase where we map your requirements, data model, and API endpoints. We deliver a detailed Roadmap in week 3 with fixed price and timeline.
The Build phase runs 8-12 weeks with biweekly demos. The Release phase includes load testing, security audit, and deployment to your AWS or GCP account. Post-launch, we offer 30 days free support.
What ships with your Node.js API
No hidden deliverables. Every project includes these items by default.
Our standard delivery includes everything you need to run your API in production from day one.
You get full ownership of all artifacts. No licensing fees, no vendor lock-in.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab
- Docker containers for local dev and production
- Swagger/OpenAPI 3.0 documentation
- Unit tests (Jest) with 90%+ coverage
- Integration tests for all endpoints
- Sentry error tracking and alerts
- ELK stack logs (Elasticsearch, Logstash, Kibana)
- Deployment scripts for AWS/GCP/Azure
- Postman collection for manual testing
What we ship in this practice.
Payment processing API for fintech startup
Built a RESTful API handling 150 transactions/second with idempotency and PCI-DSS compliance. Reduced manual reconciliation from 8 hours to near zero. Stack: Node.js, PostgreSQL, Redis, Stripe.
Real-time EHR API for telemedicine platform
Developed a HIPAA-compliant WebSocket API for live patient monitoring. Achieved <100ms latency for 5,000 concurrent users. Stack: Node.js, Fastify, Socket.io, MongoDB, AWS IoT.
GraphQL API for ecommerce product catalog
Created a federated GraphQL API aggregating data from 3 legacy systems. Cut page load times by 60%. Stack: Apollo Server, GraphQL Federation, PostgreSQL, Redis, Shopify API.
Microservices API for logistics platform
Decomposed a monolith into 15 microservices with event-driven architecture. Increased deployment frequency from monthly to daily. Stack: Node.js, NestJS, RabbitMQ, Docker, Kubernetes, AWS SQS.
Internal API for HR system at enterprise
Built a private REST API connecting ADP, Workday, and internal tools. Automated employee onboarding from 3 weeks to 2 days. Stack: Node.js, Express, Okta OAuth2, Azure SQL, SendGrid.
Third-party API wrapper for real estate MLS
Created a unified API over 8 regional MLS systems with normalized data models. Reduced integration time for new partners from 4 weeks to 2 days. Stack: Node.js, Rete.js, MariaDB, Redis cache.
Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Average API project costs $120K-$200K.
Senior engineers only
Every developer on your project has 10+ years of experience and a deep background in Node.js, Express, PostgreSQL, and Docker. No junior staff, no code reviews of juniors by seniors.
Compliance built in, not bolted on
We ship APIs with HIPAA controls (audit logs, encryption, BAA), PCI-DSS (tokenization, PCI scope), and SOC 2 (access controls, monitoring). We have handled 15+ compliance audits.
Full code ownership
You own 100% of the code. We push to your GitHub from day one. No license fees, no royalties, no usage limits. You can deploy, modify, or resell the API without restrictions.
Start in 1-2 weeks
Discovery calls are free and take 30 minutes. We can start a 2-week Discovery phase within 10 business days of signing. No long sales cycles or discovery fees.
Transparent weekly demos
Every two weeks we show working endpoints on your staging environment. You see progress in real time. No black-box development. Average client gives feedback on 4-5 sprints.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
