Premium Node.js API Development ServicesAPI Development
We build high-performance Node.js APIs for data-intensive applications. Get your MVP in 8-12 weeks with fixed pricing and senior engineers.
IRPR builds premium Node.js API development services for startups and enterprises. We use Node.js with Express, Fastify, and Apollo Server to create REST, GraphQL, and WebSocket APIs that handle thousands of requests per second. Our APIs integrate with PostgreSQL, Redis, Stripe, and AWS Lambda.
Projects ship in 8-12 weeks with fixed pricing from $80K to $250K. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards. Every API includes automated testing, CI/CD pipelines, and 99.9% uptime SLA.
Clients who hire us include CTOs scaling a SaaS product, founders launching an MVP in 12 weeks, enterprise teams migrating legacy APIs to Node.js, and compliance officers needing HIPAA-compliant backend services.

Node.js API Development by the Numbers
Our track record speaks for itself with proven outcomes for every project.
Over 200 products have shipped using our Node.js API services. Teams in more than 50 countries rely on our APIs for mission-critical operations.
The average MVP takes 12 weeks and costs between $80K and $250K. We maintain a 98% on-time delivery rate and 99.9% uptime across all production APIs.
How Generic Dev Shops Compare to IRPR
Not all Node.js development teams deliver the same quality and reliability.
Many agencies use junior developers, vague estimates, and inconsistent code quality. Their APIs often lack documentation, monitoring, or security hardening.
IRPR assigns senior engineers only, provides a fixed price after the Roadmap phase, and ships with production-grade CI/CD, monitoring, and compliance documentation.
- Junior developers or offshore teams
- Hourly billing with scope creep
- No dedicated project manager
- Minimal API documentation
- No automated load testing
- You own zero code until final payment
- Senior engineers with 10+ years experience
- Fixed price locked after Roadmap phase
- Dedicated PM with weekly demos
- OpenAPI/Swagger docs auto-generated
- CI/CD pipeline with k6 load tests
- Source code delivered in week 1
Our 4-Phase API Development Process
From idea to production in 8-12 weeks with clear milestones.
Every project starts with a 2-day discovery sprint to align goals. We then build a detailed Roadmap that defines scope, timeline, and fixed price.
During construction we iterate in 2-week sprints with demos. Launch includes infrastructure setup, monitoring, and a 30-day warranty.
What Ships with Every Node.js API Project
Every deliverable is production-ready and fully documented.
Our standard set of deliverables ensures your team can maintain and scale the API without dependency on IRPR. You own everything from day 1.
All projects include infrastructure-as-code, automated tests, and a monitoring dashboard. We also include a 30-day post-launch support period.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated unit and integration tests (Mocha, Jest)
- API documentation via OpenAPI (Swagger) or GraphQL schema
- Docker containers and Docker Compose for local dev
- Deployment scripts for AWS (ECS/Lambda) or GCP (Cloud Run)
- Sentry error tracking and Datadog APM integration
- Load test results with k6 (10,000 concurrent users)
- Postman collection for manual testing
- Security audit report (OWASP top 10, dependency scanning)
What we ship in this practice.
Real-time Chat API for a Healthcare Platform
Built a WebSocket-based chat API using Node.js + Socket.IO that processes 500 messages/minute. Integrated with Epic EHR for HIPAA-compliant messaging. Reduced provider response time by 3 hours.
Payment Gateway API for Fintech Startup
Developed a PCI-DSS compliant REST API with Stripe Connect and Plaid. Handles 2,000 transactions/hour with 200ms latency. Scaled from zero to $2M monthly processing in 6 months.
Product Catalog API for Ecommerce Brand
Created a GraphQL API using Apollo Server and Elasticsearch that supports 50,000 SKUs. Real-time inventory sync with Shopify and Amazon. Cut product page load time from 3s to 200ms.
Multi-tenant SaaS API for Analytics Platform
Built a microservices API with Fastify and PostgreSQL that handles 10,000 tenants. Used Redis for caching and Bull for background job processing. Achieved 99.99% uptime over 12 months.
Supply Chain Tracking API for Logistics Company
Developed WebSocket + REST hybrid APIs to track 10,000+ shipments daily. Integrated with FedEx, UPS, and USPS. Reduced manual tracking time by 8 hours per week.
Consumer Lending API for Real Estate Platform
Built a Node.js API for loan origination and underwriting. Connected to Plaid, LexisNexis, and FICO. Reduced loan approval time from 2 weeks to 24 hours.
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, and no scope creep charges. You know the cost upfront.
Senior engineers only
We assign 3 senior Node.js engineers per project, each with 10+ years of experience. No juniors, no fresh graduates, no offshore training periods.
Compliance-ready from day 1
We build HIPAA-compliant, PCI-DSS compliant, and SOC 2 compliant APIs. Our standard templates include audit logging, encryption, and access controls.
You own the code
Source code is written in your repository from the first sprint. You own all intellectual property and can deploy independently after launch.
Dedicated project manager
A PM runs your project with weekly demos and daily async updates via Slack. You always know progress, blockers, and next steps.
Start in 1-2 weeks
We can kick off most projects within 10 business days. Our onboarding process includes infrastructure setup, team introduction, and a shared roadmap.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
