Why Choose an Expert Node.js Backend Development Firm
Your backend is the foundation of your product. A bad backend costs you users, revenue, and time.
IRPR has shipped 200+ backend systems for clients in 50+ countries. We use Node.js because it handles 10,000+ concurrent connections with a single thread using an event-driven, non-blocking I/O model. That means lower latency and lower server costs for you.
We build backends that scale from day one. Our engineers write clean TypeScript, implement automated CI/CD pipelines with GitHub Actions, and deploy to AWS ECS or Google Cloud Run. Every project includes Sentry error tracking and Datadog monitoring.
Generic Dev Shop vs Expert Node.js Backend Firm
Not all Node.js developers are equal. Here is what you get with a generic shop versus IRPR.
Generic dev shops often assign junior developers who learn Node.js on your dime. They write untyped JavaScript, skip testing, and deliver a backend that crashes under load. You pay hourly for their learning curve.
IRPR assigns senior engineers with 7+ years of Node.js experience. We write TypeScript with 90%+ test coverage, use automated load testing with k6, and deliver a production-ready backend in 8-12 weeks at a fixed price.
- junior or mid-level developers
- no TypeScript, plain JavaScript
- hourly billing, no fixed price
- no load testing or monitoring
- no compliance (HIPAA, PCI, SOC 2)
- code ownership often unclear
- senior Node.js engineers only
- TypeScript with 90%+ test coverage
- fixed price from $80K to $250K
- k6 load testing + Datadog monitoring
- HIPAA, PCI-DSS, SOC 2 compliant
- full source code ownership
How We Build Your Node.js Backend
We follow a proven 4-phase process to deliver your backend on time and on budget.
Every project starts with a 2-week Roadmap phase where we define the API contract, database schema, and deployment architecture. You get a fixed price and a detailed timeline before any code is written.
We then build the backend in 6-10 weekly sprints, delivering a working API endpoint every week. You review progress in real time on a staging environment. No surprises.
What Ships With Your Node.js Backend
Every project includes a complete production-ready backend with all the tooling you need to run it.
We do not just write code. We ship a full backend system that includes CI/CD pipelines, monitoring, error tracking, and documentation. You can deploy to production on day one.
All source code is in your GitHub or GitLab repository. You own everything. No lock-in, no license fees.
- Full source code in your private Git repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated test suite with 90%+ coverage
- OpenAPI or GraphQL schema documentation
- Docker containers for local and production deployment
- Sentry error tracking and alerting
- Datadog or CloudWatch monitoring dashboard
- k6 load testing scripts and results report
- Postman or Insomnia API collection
- Deployment guide and runbook
What we ship in this practice.

Why teams hire us.
Senior Engineers Only
Every engineer on your project has 7+ years of Node.js experience. We do not outsource or use junior developers. You get a senior architect who writes production-ready TypeScript.
Fixed Price, No Hourly Billing
You get a fixed price quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. The price is locked for the entire project.
8-12 Week Delivery
Most backends ship in 8-12 weeks. We run 1-week sprints with a working API endpoint delivered every Friday. You see progress every week and can adjust priorities.
Production-Ready From Day One
Every backend ships with CI/CD, monitoring, error tracking, and load testing. You can deploy to production immediately after handover. No technical debt left behind.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant backends by default. Our infrastructure uses encrypted databases, secure authentication, and audit logging. No retrofitting needed.
Full Code Ownership
You own all source code, documentation, and deployment scripts. No license fees, no vendor lock-in, no recurring royalties. You can take the code to any team or deploy it yourself.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
