Best Node.js API Development ConsultantsAPI Development
We build production-grade Node.js APIs in 8-12 weeks. Fixed price, senior engineers only, no fluff.
IRPR builds Node.js APIs for startups and enterprises. We use Express, Fastify, NestJS, and Apollo for GraphQL. Every API is designed for scalability, security, and maintainability from day one.
A typical API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance like HIPAA, PCI-DSS, and SOC 2. You get full ownership of the code and a production-ready deployment.
Our clients include CTOs at funded startups who need a rapid MVP, engineering leads at fintech companies requiring PCI-compliant APIs, product managers at healthcare platforms needing HIPAA-safe integrations, and SaaS founders scaling from 0 to 10,000 users.
Types of software we ship.
REST API Development
Stateless, resource-oriented APIs with Express or Fastify. Includes Swagger/OpenAPI docs and JWT auth.
GraphQL API Development
Flexible GraphQL backends with Apollo Server or Yoga. Designed for complex queries and real-time subscriptions.
Microservices API
Decoupled microservices using Node.js, Docker, and Kubernetes. Each service has its own database and API gateway.
Real-time API (WebSocket)
Low-latency WebSocket APIs with Socket.io or uWebSockets.js. Used for live chat, notifications, and dashboards.
Third-Party API Integration
Integrate with Stripe, Salesforce, HubSpot, or custom endpoints. Includes retry logic, rate limiting, and webhooks.
API Gateway Development
Centralized gateways using Kong, Express Gateway, or custom middleware. Handles auth, logging, and rate limiting.
Internal API for SaaS Products
Private APIs for internal tools and admin panels. Built with Node.js, Redis caching, and PostgreSQL.
Public API for Platforms
Developer-facing public APIs with versioning, documentation portal, and usage analytics. Supports OAuth 2.0 and API keys.
We build for every business type.

Node.js API Development by the Numbers
We measure everything. Our team has delivered over 200 Node.js APIs across 50 countries.
Every project starts with a clear scope in the Roadmap phase (week 2). You see the exact timeline, delivery dates, and fixed price before we write a line of code. No surprises.
Our APIs maintain 99.9% uptime in production. We use automated testing with Jest, load testing with k6, and monitoring with Datadog. Senior engineers review every pull request.
Generic Agency vs IRPR: The Real Difference
Not all Node.js consultants deliver the same. Here is what sets us apart.
Generic dev shops often assign junior developers, use hourly billing, and skip compliance. They deliver monolithic APIs that break under load. You end up paying for refactors.
IRPR assigns senior engineers only (7+ years experience). We use fixed pricing, write 90%+ test coverage, and build for HIPAA, PCI, or SOC 2 out of the box. Your API scales from day one.
- Junior or mid-level developers
- Hourly billing with scope creep
- No compliance expertise
- No automated testing
- No CI/CD pipeline included
- Weak documentation
- Senior engineers only (7+ years)
- Fixed price per project
- HIPAA, PCI, SOC 2 ready
- 90%+ test coverage Jest
- CI/CD on GitHub Actions included
- OpenAPI docs and Postman collections
How We Build Your Node.js API in 8-12 Weeks
Our process has four clear phases. You stay in control the entire time.
Week 1-2: Idea phase. We map your requirements, user flows, and data model. You get a detailed Roadmap with exact deliverables and the fixed price. No code yet, no risk.
Week 3-10: Product phase. Senior engineers build the API in 2-week sprints. You see progress in a staging environment. We deploy to production in week 11-12 with full monitoring.
What Ships with Every Node.js API Project
We do not deliver half-finished code. Every project includes these items by default.
You own everything. Source code, tests, configuration, and documentation are yours. We push to your GitHub repo from day one.
Production deployment is part of the price. You get a fully running API with monitoring, logging, and error tracking from the start.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- OpenAPI 3.0 documentation (Swagger UI)
- Postman collection for all endpoints
- 90%+ test coverage (Jest + Supertest)
- Production deployment to AWS/GCP/Azure
- Monitoring with Datadog or Sentry
- Rate limiting and authentication (JWT/OAuth)
- Database migrations and seed scripts
- 1 month of post-launch support
What we ship in this practice.
Fintech Payment Processing API
Built a PCI-DSS compliant API for a payment startup handling 10,000 transactions/day. Used Node.js, Express, Stripe Connect, and PostgreSQL. Reduced manual reconciliation by 12 hours/week.
Healthcare Patient Portal API
Created a HIPAA-safe REST API for a telemedicine platform serving 50 clinics. Used Fastify, MongoDB, and AWS Lambda. Achieved 99.95% uptime and passed external security audit in 2 weeks.
E-commerce Product Catalog API
Delivered a GraphQL API for a fashion retailer with 200K SKUs. Used Apollo Server, Redis caching, and Elasticsearch. Cut product search latency from 3 seconds to 200ms.
SaaS Multi-Tenant User Management API
Built a multi-tenant Node.js API for a B2B SaaS with 150 tenants. Used Express, PostgreSQL row-level security, and JWT. Onboarded new tenants in under 5 minutes automated.
Logistics Real-Time Tracking API
Developed a WebSocket-based tracking API for a delivery fleet with 500 drivers. Used Node.js, Socket.io, and Redis. Provided live location updates every 2 seconds.
Media Content Distribution API
Created a public REST API for a media platform serving 1 million daily requests. Used Node.js, NGINX caching, and Cloudflare. Handled 5,000 requests/second with 99.99% uptime.
Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we start.
Senior engineers only
We assign engineers with 7+ years of Node.js experience. No juniors, no offshore teams. Every line of code is reviewed by a senior architect. You get production-grade quality.
Compliance built in
We build APIs that meet HIPAA, PCI-DSS, and SOC 2 requirements from day one. Our team has passed 12+ third-party security audits. No retrofitting needed.
Async-first, no time zone games
We work async with 4-hour daily overlap with US time zones. You get daily updates in Slack or your project management tool. No endless meetings.
Product thinking, not just code
We do not just write endpoints. We ask why. Our engineers understand your domain, user needs, and business metrics. We ship APIs that solve real problems.
Full ownership, no lock-in
You own the source code, documentation, and deployment infrastructure. We push to your GitHub from sprint one. Switch providers or keep the team. No vendor lock-in.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
