Professional Node.js API Development TeamAPI Development
We build secure, high-performance Node.js APIs for your product. Get a fixed-price quote and a dedicated team of senior engineers in 2 weeks.
IRPR builds custom Node.js APIs for SaaS platforms, mobile backends, and microservices. We use Express.js, Fastify, NestJS, and PostgreSQL or MongoDB for data storage.
We ship a production-ready API in 12-14 weeks. Pricing ranges from $80K to $250K depending on complexity, compliance needs, and the number of endpoints.
Our clients are CTOs at Series A startups needing a scalable MVP backend, product managers at healthcare companies requiring HIPAA-compliant APIs, and enterprise teams migrating legacy systems to Node.js microservices.
Types of software we ship.
RESTful API for Mobile App
Build a REST API to power your iOS or Android app. Integrate push notifications, offline sync, and third-party services like Stripe.
GraphQL API for Web Frontend
Give your frontend team full control over data fetching. Use Apollo Server and TypeGraphQL for a type-safe, performant API.
Real-Time API with WebSockets
Deliver live updates for chat, notifications, or dashboards. Built with Socket.io and Redis pub-sub for low latency.
API Gateway for Microservices
Centralize authentication, rate limiting, and routing for your microservices architecture. Use Express Gateway or Kong.
Payment Processing API
Handle subscriptions, one-time payments, and refunds securely. Integrate Stripe or Braintree with PCI-DSS compliance.
Authentication and Authorization API
Implement OAuth2, JWT, and session management. Use Passport.js or Auth0 for social login and role-based access.
Data Aggregation API
Pull data from multiple sources into a single unified endpoint. Use Node.js streams and caching with Redis.
File Upload and Processing API
Enable image uploads, video transcoding, or document parsing. Use AWS S3, Sharp for images, and Bull job queues.
We build for every business type.

Node.js API Development by the Numbers
Our team has delivered over 200 production APIs for clients in 50+ countries, with a 98% on-time delivery rate.
We track every metric that matters: API response times, error rates, uptime, and developer productivity. Our APIs typically serve 10,000+ requests per second with sub-100ms latency.
We have built APIs for startups that scaled from zero to 1 million users. Every project includes automated monitoring with Datadog and PagerDuty alerts.
Why Hire a Professional Node.js API Development Team
Most dev shops deliver code that works today but breaks tomorrow. Our approach is built for long-term production stability.
A professional API needs more than just routes and controllers. It needs authentication, rate limiting, documentation, error handling, logging, and deployment automation. We include all of that by default.
Many clients come to us after a failed attempt with a low-cost freelancer or a generalist agency. We fix the architecture, add tests, and set up proper CI/CD.
- Hourly billing with no scope control
- No security or compliance review
- No automated tests or CI/CD
- Poor or missing documentation
- No monitoring or error tracking
- Code ownership not explicitly stated
- Fixed price quoted in Roadmap phase
- HIPAA, PCI-DSS, SOC 2 ready
- Unit tests, integration tests, CI/CD via GitHub Actions
- Swagger/OpenAPI docs auto-generated
- Sentry error tracking and Datadog monitoring included
- Full code ownership, you get the repo
How We Build Your Node.js API
Our process is designed to de-risk your investment from day one.
We follow a four-phase approach: Roadmap, Build, Deploy, and Support. Each phase has fixed deliverables and a clear go/no-go decision point.
By the end of week 2, you have a detailed project roadmap with wireframes, tech stack decisions, and a fixed price. No surprises.
What You Get When You Ship Your Node.js API
Every project includes these deliverables, no extra cost.
We believe in shipping more than just code. You get documentation, monitoring, and a clear path to scale.
All source code is yours. We do not use proprietary frameworks or black boxes.
- Complete source code in your private GitHub repository
- OpenAPI/Swagger documentation generated from code
- Postman collection with all endpoints and examples
- Unit tests and integration tests with 90%+ coverage
- CI/CD pipeline using GitHub Actions or CircleCI
- Sentry error tracking and Datadog monitoring setup
- Dockerized development environment
- Database migration scripts (PostgreSQL or MongoDB)
- Deployment guide and runbook
- 30-day post-launch support window
What we ship in this practice.
Real-Time Chat API for Social App
Built a WebSocket-based chat API using Node.js, Socket.io, and Redis. Handled 10,000 concurrent users with under 200ms latency. Reduced message delivery time by 40% compared to the previous REST polling approach.
Payment Gateway API for Fintech Startup
Developed a PCI-compliant payment API integrated with Stripe and Plaid. Processed $2M in transactions in the first month. Achieved 99.99% uptime and reduced transaction failures by 25% with automatic retries.
Patient Data Exchange API for Healthcare
Created a HIPAA-compliant FHIR API for a telemedicine platform. Enabled secure sharing of patient records between 50 clinics. Eliminated manual data entry saving 10 hours per clinic per week.
Product Catalog API for E-Commerce
Built a GraphQL-powered product API using NestJS and Elasticsearch. Served 5,000 requests per second with sub-100ms response times. Powered the search and filter experience for 1 million monthly visitors.
API Gateway for SaaS Microservices
Designed an API gateway using Express Gateway and Redis that unified 12 internal microservices. Added rate limiting, authentication, and request logging. Reduced inter-service latency by 30%.
Video Transcoding API for Media Platform
Implemented a file processing API using Node.js, Bull queues, and FFmpeg on AWS Lambda. Converted 10,000 videos per day to multiple resolutions. Cut processing costs by 60% compared to EC2-based transcoding.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a firm quote at the end of the Roadmap phase (week 2). No time tracking, no billing arguments. You know the cost before we write a line of production code.
Senior Engineers Only
We do not staff juniors or offshore novices. Every engineer has 8+ years of Node.js experience and has shipped at least 5 production APIs. Our team is based across the US, Europe, and India with 4+ hour overlap.
Compliance Built In
We have built APIs for HIPAA, PCI-DSS, and SOC 2 environments. We include encryption at rest and in transit, audit logs, and role-based access control by default.
Full Code Ownership
You own every line of code. We put it in your GitHub account from day one. No proprietary libraries, no license fees, no vendor lock-in.
Rapid Kickoff
We can start within 1-2 weeks of signing the agreement. You get a dedicated project manager, a Slack channel, and daily standups from day one.
Long-Term Support
After launch, we stay for 30 days of free bug fixes and optimization. We offer ongoing maintenance at a fixed monthly rate if you need it.
