Hire the top Node.js backend development teambackend development
We build production-grade Node.js backends for B2B SaaS, fintech, and ecommerce. Senior engineers only, fixed price, 8-12 week delivery.
IRPR is a software development studio that builds server-side applications using Node.js, Express, NestJS, and TypeScript. We design RESTful APIs, GraphQL gateways, microservices, and real-time systems with WebSocket support. Our team ships production-grade backend code for web apps, mobile apps, and AI chatbots.
Every project follows a fixed-price model starting at $80,000. The Roadmap phase (week 2) gives you a fixed quote and a detailed plan. Typical projects finish in 8-12 weeks. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA standards as needed.
We work with CTOs of B2B SaaS companies who need a scalable backend for their platform, startup founders building an MVP for investor demos, VPs of Engineering at enterprise firms migrating legacy systems to Node.js, and product managers who need a dedicated team to ship fast without agency overhead.

Node.js backend development services by the numbers
We have shipped 200+ products for clients in 50+ countries. Our Node.js teams deliver on time and on budget.
Since 2016, IRPR has built Node.js backends for startups and enterprises. Our engineers have worked on projects ranging from single-microservice APIs to systems handling 10,000 requests per second. We use TypeScript, NestJS, Prisma, and Redis on every project.
Our process is designed for speed and quality. We ship an MVP in 8-12 weeks. Our on-time delivery rate is 98%. We provide a fixed price after the Roadmap phase so you know the cost upfront.
The difference between IRPR and a generic Node.js development shop
Not all teams deliver the same quality. Here is why IRPR stands out as a top Node.js backend development team.
Generic agencies often use junior developers, charge by the hour, and deliver code with no tests. They promise fast delivery but miss deadlines. Their code is hard to maintain and lacks proper error handling.
IRPR assigns senior engineers only (average 10+ years of experience). We write automated tests for every endpoint, set up CI/CD pipelines, and document APIs with OpenAPI specs. Our code ships with Sentry error tracking and Datadog monitoring.
- Hourly billing with scope creep
- Junior developers with 2 years of Node.js
- No automated tests in the first sprint
- Deployments done manually via SFTP
- No documentation or Swagger specs
- No monitoring or error tracking setup
- Fixed price after Roadmap phase
- Senior Node.js engineers with 10+ years experience
- 200+ unit and integration tests per project
- CI/CD on GitHub Actions with auto-deploy
- OpenAPI 3.0 docs generated from code
- Sentry + Datadog for production monitoring
How we build your Node.js backend in 4 phases
Our process is designed to reduce risk and deliver a production-ready backend quickly.
Every engagement follows a proven framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and milestones. You see progress every week.
The Roadmap phase (week 2) gives you a full architecture diagram, a fixed price, and a timeline. There are no surprises. We start coding in week 3.
What ships with every Node.js backend project
Deliverables are not just code. You get a complete production system with documentation and monitoring.
We believe in shipping systems, not just code. Every project includes infrastructure as code, monitoring, and a runbook. You can hand it to your internal team or keep us for maintenance.
Our standard delivery package ensures you have everything needed to run the backend in production from day one.
- Source code in your private GitHub repository with full commit history
- CI/CD pipeline on GitHub Actions with automated tests and auto-deploy
- Sentry error tracking with alerting rules configured
- Datadog dashboard for API metrics (latency, error rates, request volume)
- PostgreSQL or MongoDB database schema migration scripts
- Swagger/OpenAPI documentation served via a `/docs` endpoint
- Docker Compose setup for local development
- Production deployment on AWS ECS, GCP Cloud Run, or Azure App Service
- Load test results using k6 showing 10K concurrent connections
- Runbook with incident response procedures and restore steps
What we ship in this practice.
Real-time order tracking backend for a logistics platform
Built a WebSocket server using Node.js and Socket.io that pushed live location updates to 5,000 drivers. Integrated with Google Maps API and stored trips in PostgreSQL. Reduced customer support calls by 40%.
HIPAA-compliant patient data API for a telemedicine startup
Designed a RESTful API with NestJS, TypeORM, and PostgreSQL. Implemented audit logging and encryption at rest. Passed HIPAA audit on first submission. Handles 50,000 patient records daily.
Payment processing microservice for a subscription SaaS
Built a Node.js microservice with Stripe Billing and idempotent webhooks. Processed $2M in recurring payments monthly with 99.99% uptime. Reduced billing errors by 90%.
GraphQL gateway for a multi-vendor ecommerce platform
Created an Apollo Federated GraphQL gateway that aggregated catalogs from 3 separate vendor databases. Improved frontend page load time by 60% and reduced API calls per page from 12 to 1.
Crypto exchange backend with real-time order book
Developed a low-latency Node.js engine for matching buy/sell orders. Used Redis for in-memory order book and PostgreSQL for trade history. Achieved 10ms average trade execution.
Live collaboration backend for an edtech whiteboard app
Built a WebSocket server using uWebSockets.js that synchronized canvas strokes for 200 concurrent users. Integrated with AWS S3 for asset storage. Decreased sync latency from 200ms to 15ms.
Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has at least 10 years of experience with Node.js and TypeScript. We do not use junior developers or offshore shops. You get a lead who has shipped production systems at scale.
Fixed price, not hourly
After the 1-week Roadmap phase, we give you a fixed price for the entire project. No hourly billing, no time tracking, no surprise invoices. If we need more work, we tell you before we do it.
Production-ready code from sprint 1
We write unit tests, integration tests, and set up CI/CD from day one. Your staging environment is live by week 3. Code is always in a deployable state.
Compliance built in: HIPAA, PCI, SOC 2
We have implemented Node.js backends that passed HIPAA audits, PCI-DSS assessments, and SOC 2 Type II reviews. We handle PHI, PCI data, and PII according to standards.
You own everything
Source code, AWS account, Docker images, domain names, and documentation belong to you. No licensing fees, no dependency on us. We provide a handover guide so your team can take over.
98% on-time delivery track record
Out of 200+ projects, 98% shipped within the agreed timeline. We use weekly demos and a shared project tracker so you see progress in real time. If we are behind, we tell you on day 1 of the delay.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
