Premium Node.js API Development FirmAPI Development
Stop rebuilding broken endpoints. Our senior Node.js engineers deliver production-ready APIs in 12 weeks flat.
IRPR builds production-grade Node.js APIs for companies that need reliability at scale. We use Express.js for REST, GraphQL for flexible data queries, and TypeScript for type safety. Every API ships with automated CI/CD, integrated monitoring, and full documentation.
From scoping to release takes 12 weeks on average. Fixed pricing starts at $80K for a minimum viable API and goes up to $250K for complex multi-service architectures. We handle compliance: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS.
CTOs hire IRPR when they need a scalable backend fast. Startup founders build their full product backend in one shot. SaaS companies pay us to refactor monolithic Node.js APIs into microservices. Enterprise teams outsource their entire API layer because their in-house team is too slow.
Types of software we ship.
REST API
Stateless endpoints for CRUD operations. Uses Express.js with JWT auth. Default for mobile and web apps.
GraphQL API
Query language for flexible data fetching. Uses Apollo Server with schema stitching. Reduces over-fetching by 60%.
Microservices API
Decoupled services communicating via gRPC or message queues. Each service scales independently. Uses Docker and Kubernetes.
WebSocket API
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio. We handle auth, rate limits, error handling, and webhooks.
Internal API Gateway
Single entry point for all internal microservices. Handles authentication, rate limiting, caching. Uses NGINX or Kong.
B2B API for Partners
Expose your data to external partners with API keys, usage tracking, and developer documentation. Built with OpenAPI specs.
Serverless API
Event-driven functions on AWS Lambda or Vercel. Pay only per request. Scales to zero when not in use.
We build for every business type.
Ecommerce
SaaS Platforms
Healthcare
Fintech & Payments
Logistics & Travel
Why hire a premium Node.js API development firm
Building a production API is more than writing routes.
Most agencies deliver a running Node.js server with basic CRUD. IRPR delivers an API that stays online, handles traffic spikes, and integrates with your existing stack. Every API ships with automated tests, error tracking via Sentry, and health checks.
We design for scale from day one. Our APIs use Redis caching, database indexing, and connection pooling. A travel booking API I built for a New York client now handles 50,000 requests per minute without a single timeout in 18 months.
How generic dev shops fail at Node.js APIs
Most agencies take shortcuts that cost you later.
Generic shops write endpoints that work on day one but break when traffic grows. They skip monitoring, ignore error handling, and deliver undocumented code. You end up with a black box that no one on your team understands.
IRPR treats your API like a product. We write TypeScript with strict types, add automated tests for every endpoint, and include a Postman collection and OpenAPI spec. Your internal team can take over in one week.
- Delivers undocumented endpoints
- No automated tests
- Single server, no load balancing
- No monitoring or alerting
- Hours-based billing with scope creep
- Code in their repo, you have to request files
- Full OpenAPI spec and Postman collection
- 95% test coverage enforced via CI
- Auto-scaling on Kubernetes or ECS
- Sentry + Datadog from day one
- Fixed price with scope locked in Roadmap phase
- Source code in your repo from day one
How we build your Node.js API in 12 weeks
Four phases from idea to live API.
Week 1-2 Roadmap phase: we map every endpoint, data model, and integration. You get a fixed price and a timeline before any code is written. If your needs change, we adjust the scope before development starts.
Week 3-12 Product phase: our senior engineers build in two-week sprints. You see working endpoints every 14 days. By week 10 we run load testing. By week 12 the API is deployed to production with monitoring active.
What you get when you hire IRPR
Every deliverable required to run and maintain your API.
Ships by default includes source code, documentation, and infrastructure. Your internal team can pick it up and make changes immediately.
We also include training and a two-week warranty period. If something breaks in production, we fix it within 24 hours.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions with automatic tests
- Sentry error tracking and alerting
- Datadog monitoring with custom dashboards
- OpenAPI 3.0 specification
- Postman collection with sample requests
- Deployment scripts for AWS or GCP
- Database migration scripts and seed data
- Admin dashboard with usage metrics
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly billing
Every API project gets a fixed quote during the Roadmap phase (week 2). No hourly rates, no surprise invoices. If the scope changes, we adjust the price before writing new code.
Senior engineers only, no juniors
Every engineer on your project has 10+ years of experience. We don't outsource to offshore teams or hire junior developers. You get a senior lead who stays on your project end to end.
Source code ownership from day one
Code lives in your GitHub repository from the first commit. You own everything. No licensing fees, no proprietary frameworks. You can take the code and walk away at any time.
Built for compliance from day one
We design APIs with compliance baked in. HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS. Our team includes a compliance engineer who audits every endpoint before release.
12-week delivery guarantee
From kickoff to production deployment in 12 weeks. We have shipped over 200 products on time. If we don't deliver on schedule, you don't pay for the extra sprints.
Production monitoring included
Every API includes Sentry error tracking and Datadog dashboards. We set up alerts for 4xx errors, 5xx errors, and latency spikes. You know exactly when something breaks.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
