Why Node.js Is the Backbone of Modern Backend Development
Node.js powers high-throughput, event-driven applications that scale with your business.
Node.js uses a non-blocking I/O model that handles 10,000+ concurrent connections on a single thread. This makes it ideal for real-time apps, APIs, and microservices. IRPR uses Node.js with Express.js, NestJS, and Fastify to build backends that stay fast under load.
Our Node.js backends integrate with PostgreSQL, Redis, and MongoDB for data persistence. We add monitoring with New Relic and Sentry to catch errors before users do. Every backend ships with a CI/CD pipeline on GitHub Actions.
How IRPR Delivers Node.js Backends Differently
Most agencies bill hourly and hand off incomplete code. We do the opposite.
We start with a 2-week Roadmap phase where we spec every endpoint, data model, and integration. You get a fixed price and a clear timeline before any code is written. No surprises, no scope creep.
Our engineers are all senior level with 10+ years of experience. Every project has a dedicated tech lead who reviews every pull request. We ship the backend into your own AWS or GCP account with full ownership.
- Hourly billing with no cap
- Junior developers on your project
- No compliance knowledge (HIPAA, PCI)
- Code lives in their repo
- No monitoring or CI/CD setup
- Handoff with minimal documentation
- Fixed price from $80K to $250K
- Senior engineers only (10+ years)
- Built-in HIPAA, PCI, SOC 2 compliance
- Full code ownership in your repo
- CI/CD pipeline with GitHub Actions and Sentry
- Complete API documentation and deployment guide
Our Node.js Backend Development Process
From idea to production in 8-12 weeks with no surprises.
Every project follows a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price. You know exactly what you get and when.
The Roadmap phase (week 2) produces a detailed spec with API contracts, database schema, and integration points. The Product phase builds the backend in 6-10 weeks with weekly demos. The Release phase deploys to production with load testing and monitoring.
What Ships with Every Node.js Backend
You get a production-ready backend, not a half-finished prototype.
Every IRPR backend includes source code in your repo, a CI/CD pipeline, monitoring, and error tracking. We also provide API documentation and a deployment runbook so your team can operate it independently.
Our backends are built with compliance in mind. If you need HIPAA, PCI, or SOC 2, we bake the controls into the architecture from day one. No retrofit, no extra cost.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking
- New Relic or Datadog performance monitoring
- PostgreSQL or MongoDB database with migrations
- Redis for caching and session management
- REST or GraphQL API with Swagger/GraphiQL docs
- Docker containerization and docker-compose
- Deployment runbook for AWS or GCP
- 30-day post-launch support
What we ship in this practice.
Real-time analytics dashboard for logistics
Built a Node.js backend with WebSockets and Redis to stream shipment data to a live dashboard. Reduced report generation from 4 hours to 2 minutes. Tech stack: Node.js, Socket.io, Redis, PostgreSQL.
Payment processing backend for fintech startup

HIPAA-compliant telemedicine platform
Built a secure Node.js backend for video consultations, patient records, and e-prescriptions. Passed HIPAA audit on first try. Tech stack: Node.js, Fastify, PostgreSQL, Twilio Video.
Multi-tenant SaaS backend for CRM
Created a Node.js backend with tenant isolation, role-based access, and Stripe subscription billing. Onboarded 50+ tenants in the first month. Tech stack: Node.js, NestJS, PostgreSQL, Stripe.
Ecommerce backend with real-time inventory
Developed a Node.js backend for a marketplace with real-time inventory sync across 10 warehouses. Reduced overselling by 99%. Tech stack: Node.js, Express.js, MongoDB, RabbitMQ.
Serverless backend for mobile app
Built an AWS Lambda-based Node.js backend for a fitness app with 500,000 users. Auto-scales to zero during idle and handles 50,000 requests per minute. Tech stack: Node.js, AWS Lambda, DynamoDB, API Gateway.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
All IRPR engineers have 10+ years of experience. No juniors, no offshore teams. Every project has a dedicated tech lead who reviews every pull request and enforces code quality.
Full code ownership
You own the source code from day one. We push to your GitHub repo, not ours. No licensing fees, no lock-in. You can take the code to any team after launch.
8-12 week delivery guarantee
We ship production-ready backends in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects deliver on time.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 controls into the architecture from the start. No retrofitting, no extra cost. We have shipped 30+ compliant backends.
Post-launch support included
Every project includes 30 days of post-launch support. We fix bugs, answer questions, and help your team take over. After that, we offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
