Leading Node.js API Development CompanyNode.js API
We build production-grade APIs that scale to millions of requests. Fixed price, senior engineers, delivered in 8-12 weeks.
IRPR builds Node.js APIs that handle real traffic - from secure REST endpoints to real-time GraphQL subscriptions. We use Express, NestJS, Postgres, Redis, and Kafka to deliver fast, reliable backends.
Every API ships in 8 to 12 weeks with a fixed price between $80,000 and $250,000. We support HIPAA for healthcare, PCI-DSS for fintech, and SOC 2 for SaaS. Senior engineers write every line of code.
Startups building their first API hire us for speed. Enterprise teams hire us to replace slow or broken integrations. SaaS founders hire us when they need a scalable backend in weeks, not months.
Types of software we ship.
REST API
Stateless HTTP APIs using Express or Fastify with JWT auth, rate limiting, and OpenAPI docs. Deployed on AWS ECS.
GraphQL API
Schema-first GraphQL APIs with Apollo Server, Nexus, or TypeGraphQL. Batching, caching, and real-time subscriptions included.
WebSocket API
Real-time bidirectional APIs using Socket.IO or WebSocket protocol. Used for chat, live dashboards, and notifications.
Microservices API
Decoupled services communicating via RabbitMQ or Kafka. Each service has its own data store and scales independently.
Third-Party API Integration
Connect your system to Salesforce, Stripe, HubSpot, or custom APIs. Work in days, not months.
API Gateway
Centralized gateway with Kong or Nginx for auth, routing, rate limiting, and logging across multiple upstream services.
Real-Time Data API
Streaming APIs using Server-Sent Events or Kafka Connect. Deliver live stock prices, sensor data, or social feeds.
Serverless API
Lambda functions with AWS API Gateway or Vercel. Auto-scales from zero to peak without managing servers.
We build for every business type.
e-commerce
healthcare
fintech
SaaS
logistics
Why you need a leading Node.js API development company
Your API is the backbone of your product. A badly built API slows every feature.
A poorly designed API causes 3x more bugs in frontend code, according to Postman's 2023 survey. Restructuring it later costs 4x more than building it right the first time. IRPR designs your API schema in the Roadmap phase (week 2) and validates it with contract testing.
Our APIs handle 10,000 requests per second with 99.9% uptime on AWS. We use Redis caching to keep p95 latency under 50ms. Every endpoint includes rate limiting, authentication, and detailed error responses.
Generic dev shops vs a leading Node.js API company
Most agencies deliver code you can't trust. IRPR delivers APIs you can ship to production immediately.
Generic shops rush to code without a design. They use untyped JavaScript, skip integration tests, and hand over a half-documented mess. IRPR writes every API in TypeScript with automated tests that achieve 90% code coverage.
We enforce strict coding standards from day 1. Every commit runs through a CI/CD pipeline with linting, security scanning, and load tests. You get full ownership of the codebase and infrastructure.
- No API contract before coding
- Plain JavaScript with runtime errors
- Zero automated tests
- No rate limiting or auth by default
- Delayed by 3+ months
- Hourly billing with no budget cap
- OpenAPI spec approved before build
- TypeScript with strict types
- 90% test coverage (unit + integration)
- JWT, rate limiting, and CORS baked in
- Delivered in 8-12 weeks fixed
- Fixed price from $80K to $250K
How we build your Node.js API
Our process from idea to production takes 8 to 12 weeks, not months of uncertainty.
We use a four-phase framework that de-risks every step. Each phase ends with a clear deliverable you approve before the next begins. No guesswork, no scope creep.
The Roadmap phase produces a fixed price contract. The Product phase iterates in 2-week sprints with live demos. By Release, your API is deployed and monitored with Sentry and Datadog.
What ships with every Node.js API
Every project includes production-grade tooling out of the box. No extra cost, no hidden add-ons.
We don't just hand over code. We hand over a running system with monitoring, logging, and alerting. You get everything needed to operate in production.
All infrastructure is defined as code using Terraform or Pulumi. You can redeploy in any region without manual steps.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (90% coverage)
- Sentry error tracking and Datadog APM
- OpenAPI (Swagger) documentation
- Terraform infrastructure code (AWS only)
- Rate limiting, JWT auth, CORS configuration
- Dockerized services with docker-compose example
- Postman collection for testing
- One-week warranty support after launch
What we ship in this practice.
Real-time order tracking API for a logistics startup
Built a WebSocket-based API that streams order status from warehouse scanners to customer apps. Reduced support calls by 40% and handled 500 concurrent connections. Tech stack: Node.js, Redis, Socket.IO, AWS ECS.
HIPAA-compliant patient data API for a telehealth company
Developed a REST API with FHIR resources and audit logging for 50 clinics. Cut integration time with Epic from 3 months to 5 weeks. Tech stack: NestJS, PostgreSQL, AWS HealthLake, Sentry.
Payment processing API for a fintech platform
Created a PCI-DSS Level 1 compliant API handling $2M in monthly transactions. Achieved 99.99% uptime with automatic failover. Tech stack: Express, Stripe Connect, MongoDB, Kong gateway.
GraphQL API for a SaaS analytics dashboard
Designed a schema-first GraphQL API that reduced frontend load times by 60%. Used DataLoader to batch database queries and keep p99 under 100ms. Tech stack: Apollo Server, PostgreSQL, Redis, AWS Lambda.
Third-party integration API for an e-commerce retailer
Built a middleware API that syncs inventory between Shopify and 12 warehouses via ShipStation. Eliminated manual stock updates, saving 20 hours per week. Tech stack: Node.js, Bull queue, Shopify API, PostgreSQL.
Microservices API for a media streaming platform
Architected a microservices ecosystem with separate services for content catalog, user sessions, and billing. Scaled to 1M daily active users on launch. Tech stack: NestJS, Kafka, Cassandra, Docker Swarm.
Why teams hire us.
Senior engineers only
Every developer on your project has 7+ years of Node.js experience. We don't outsource or use junior staff. You talk directly to the engineer building your API.
Fixed price, not hourly
You get a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price is locked from day one.
Production-ready from day 1
Every API is built with CI/CD, error tracking (Sentry), APM (Datadog), and infrastructure as code. Your team can deploy changes within minutes of handoff.
Full ownership with no lock-in
You own the source code, the infrastructure, and all credentials from day one. There is no proprietary framework or recurring license. You can take it anywhere.
Compliance built in
We have built APIs for HIPAA, PCI-DSS, and SOC 2 environments. Our engineering team knows what it takes to pass an audit. We bake compliance into the architecture, not bolt it on later.
Proven track record with 200+ products
IRPR has shipped over 200 products since 2016. Our APIs serve users in 50+ countries. 98% of projects delivered on time and on budget.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
