Experienced Node.js API Development DevelopersAPI Development
We build production-ready Node.js APIs in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR builds custom Node.js APIs for startups and enterprises. We use Node.js, Express, Fastify, PostgreSQL, MongoDB, Redis, and AWS Lambda to create scalable REST and GraphQL APIs. Every API ships with automated testing, CI/CD, and monitoring.
Our team ships a production-ready API in 8-12 weeks with fixed pricing from $80K to $250K. We handle compliance needs like HIPAA, PCI-DSS, and SOC 2. You get full source code ownership and a 30-day post-launch warranty.
CTOs hire us when their in-house team lacks Node.js API expertise. Founders use us to build their MVP fast without hiring a full team. Product managers bring us in to integrate third-party APIs or replace legacy systems. Engineering leads trust us for complex data pipelines and real-time APIs.
Types of software we ship.
REST API development
Build resource-oriented APIs with Express or Fastify. Includes versioning, rate limiting, and OpenAPI docs.
GraphQL API development
Create flexible data queries with Apollo Server or Yoga. Supports subscriptions, federation, and caching.
Real-time API development
Build WebSocket or SSE APIs for live updates. Uses Socket.IO or AWS API Gateway WebSockets.
Microservices API development
Design decoupled services with Node.js. Uses Docker, Kubernetes, and message queues like RabbitMQ or SQS.
Third-party API integration
Connect your app to Stripe, Salesforce, HubSpot, or custom APIs. Handles OAuth, webhooks, and retries.
API gateway and proxy development
Build a unified gateway with Kong or Express Gateway. Manages auth, throttling, and routing across services.
Serverless API development
Deploy Node.js APIs on AWS Lambda or Vercel. Pay per request, auto-scale, zero server management.
Data pipeline API development
Build APIs that ingest, transform, and serve large datasets. Uses Kafka, Elasticsearch, and batch processing.
We build for every business type.
SaaS platforms
Fintech applications
Healthcare systems
Ecommerce and retail
Data and analytics
What our experienced Node.js API development developers deliver
Every API project includes a full suite of production-grade components.
We start with a two-week Roadmap phase where we define endpoints, data models, and integration points. You get a fixed price and a 12-week build timeline. Our senior engineers write unit tests, integration tests, and API documentation as part of the process.
All APIs are deployed on AWS or your own infrastructure. We set up CI/CD with GitHub Actions, monitoring with Datadog, and error tracking with Sentry. You own the code from day one.
The difference between a generic dev shop and IRPR
Not all Node.js API teams deliver the same quality. Here's what sets us apart.
Generic shops often assign junior developers, use hourly billing, and skip testing. They deliver slow APIs with no documentation and leave you with unmaintainable code.
IRPR assigns senior engineers only, works on a fixed price, and ships every API with automated tests, OpenAPI docs, and a monitoring dashboard. You get a production-ready system in weeks, not months.
- Junior developers learning Node.js on your project
- Hourly billing with no cap
- No automated tests or CI/CD
- No API documentation
- Unclear ownership of code
- Slow response to issues post-launch
- Senior Node.js engineers with 5+ years experience
- Fixed price from $80K to $250K
- 100% test coverage and CI/CD pipeline
- OpenAPI 3.0 docs generated automatically
- Full source code ownership from day one
- 30-day post-launch warranty with SLA
Our 4-phase process for Node.js API development
We follow a repeatable process that de-risks your project from idea to release.
Each phase has clear deliverables and checkpoints. You know exactly what you're getting and when.
The process works for startups building an MVP and enterprises replacing legacy APIs. We adapt to your timeline and compliance needs.
What ships with every Node.js API project
You get a complete, production-ready system — not just code.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (100% coverage)
- OpenAPI 3.0 documentation
- Dockerized local development environment
- Production deployment on AWS (EC2, Lambda, or ECS)
- Sentry error tracking and Datadog monitoring
- Rate limiting and API key authentication
- Database migrations and seed scripts
- Post-launch support for 30 days
What we ship in this practice.
Subscription billing API for a SaaS startup
Built a Node.js API that handles Stripe subscriptions, webhooks, and usage metering. Reduced manual billing errors by 90%. Tech stack: Express, PostgreSQL, Stripe, Bull queue.
Real-time inventory API for an ecommerce brand
Developed a WebSocket API that syncs inventory across 3 warehouses in real time. Cut stockout incidents by 70%. Tech stack: Node.js, Socket.IO, Redis, AWS API Gateway.
HIPAA-compliant patient data API for a telehealth platform
Created a REST API for patient records, appointment scheduling, and video call initiation. Passed HIPAA audit on first submission. Tech stack: Fastify, PostgreSQL, Twilio, AWS KMS.
Payment orchestration API for a fintech company
Built an API that routes payments between 4 processors (Stripe, Square, Adyen, PayPal) for optimal fees. Saved $120K/year in transaction costs. Tech stack: Node.js, Express, PostgreSQL, Redis.
Data ingestion API for a logistics startup
Developed a high-throughput API that ingests GPS tracking data from 10,000 devices per minute. Processed 2M events daily with 99.9% uptime. Tech stack: Node.js, Kafka, Elasticsearch, AWS Lambda.
GraphQL API for a media platform
Designed a federated GraphQL API that unifies content from 5 microservices. Reduced frontend load times by 60%. Tech stack: Apollo Server, Node.js, MongoDB, Redis.
Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote after the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
Senior engineers only
We assign engineers with 5+ years of Node.js experience. No juniors, no offshore teams. Every developer has shipped at least 10 production APIs.
Full code ownership
You own all source code, documentation, and infrastructure scripts from day one. No proprietary frameworks, no vendor lock-in. You can take the code and run it anywhere.
Production-ready from week 1
We set up CI/CD, automated testing, monitoring, and error tracking in the first sprint. Your API is deployable to production from week 2 onward.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our team includes engineers who have passed audits for healthcare, fintech, and SaaS clients.
Post-launch support included
Every project comes with 30 days of post-launch support. We monitor your API, fix bugs, and help your team take over. 98% of clients extend our support contract.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
Questions clients ask first.
