Best Node.js API Development DevelopersAPI Development
Build production-grade Node.js APIs that handle millions of requests. Senior engineers ship your MVP in 8-12 weeks with fixed pricing.
IRPR builds high-performance Node.js APIs that power web and mobile applications. We use Express, Fastify, and Koa to create RESTful and GraphQL endpoints that scale to millions of requests.
Every API ships with full documentation, automated testing, and cloud deployment in 8-12 weeks. Pricing is fixed from $60,000 to $200,000 depending on complexity. We build to HIPAA, PCI-DSS, and SOC 2 standards.
We work with CTOs building SaaS backends, founders launching marketplace platforms, healthcare companies needing HIPAA-compliant APIs, and fintech firms requiring PCI-certified integrations.

Node.js API Development by the Numbers
Our track record speaks for itself.
IRPR has delivered 200+ software products across 50 countries. Every Node.js API project is built by senior engineers with a fixed price.
We maintain a 98% on-time delivery rate and an average MVP timeline of 12 weeks.
Why IRPR Beats Generic Agencies
The difference is in the details.
Most Node.js development shops rely on hourly billing and junior developers. They often miss compliance requirements and produce undocumented code.
IRPR builds APIs the right way from day one. We guarantee fixed pricing, senior-only teams, and full documentation.
- Unclear project scope
- Hourly billing surprises
- Junior developers
- No compliance expertise
- Slow iterations
- Code not documented
- Fixed price from Roadmap phase
- Senior engineers only
- HIPAA/PCI/SOC 2 built-in
- 2-week sprint cycles
- Full documentation included
- CI/CD and monitoring set up
Our Node.js API Development Process
A structured 4-phase approach that guarantees results.
We break every project into clear phases. This eliminates guesswork and keeps timelines predictable.
Each phase ends with a deliverable you can review and approve.
What Ships with Every Node.js API
These deliverables are included in every project.
You get everything needed to run and maintain the API yourself. No hidden dependencies or vendor lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking
- Postman or Insomnia API collection
- Swagger/OpenAPI documentation
- Unit tests with coverage > 80%
- Deployment on AWS/GCP/Azure
- Database schema migrations
- Post-launch monitoring dashboard
- Security audit report
What we ship in this practice.
Real-Time Chat API for a Social Platform
We built a WebSocket-based chat API using Node.js, Socket.io, and Redis. The client scaled to handle 500,000 concurrent connections with sub-100ms latency.
Payment Gateway API for a Fintech Startup
A PCI-DSS compliant API integrating Stripe and Plaid. The client processed $10M in transactions in the first 6 months. Node.js, Express, PostgreSQL.
Patient Data API for a Telehealth Platform
HIPAA-compliant API using Node.js, MongoDB, and Twilio Video. The platform onboarded 200 providers and managed 50,000 patient records.
Multi-Tenant API for a SaaS Analytics Platform
We designed a GraphQL API with Apollo Server and PostgreSQL. The client reduced data query times by 60% and added 300 new customers.
MLS Data API for a Real Estate Startup
Aggregated data from 500+ MLS feeds using Node.js and RabbitMQ. The API delivered property details in under 200ms.
Inventory Management API for an Ecommerce Brand
Built RESTful API with Node.js, Redis, and Elasticsearch. The client synchronized inventory across 5 warehouses and reduced stockouts by 90%.
Why teams hire us.
Fixed Price, Not Hourly
Every Node.js API project gets a fixed quote after the Roadmap phase (week 2). No hourly billing means no surprise invoices or scope creep charges.
Senior Engineers Only
Our team consists of senior Node.js developers with 10+ years of experience. No juniors or outsourced teams work on your project.
Compliance by Default
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs out of the box. Our 50+ healthcare and fintech projects prove we meet strict regulatory standards.
Fastest Time to Market
We ship a production-ready Node.js API in 8-12 weeks. Our structured 4-phase process eliminates delays while maintaining 98% on-time delivery.
Full Documentation and Testing
Every API comes with OpenAPI docs, Postman collections, and automated tests with 80%+ coverage. You never have to guess how an endpoint works.
Long-Term Support
After launch, we provide 30 days of free maintenance and priority support. Extended SLAs are available to keep your API running at 99.9% uptime.
Idea → Roadmap → Product → Release.
