We have built Node.js applications that handle 1 million+ requests per day, process real-time data streams, and integrate with third-party APIs like Stripe, Twilio, and AWS S3. Our average NPS score is 72.
The Difference Between IRPR and a Generic Dev Shop
Most agencies promise quality but deliver technical debt. IRPR delivers production-ready Node.js code that scales.
We have audited dozens of Node.js projects built by other agencies. The most common issues are missing error handling, no automated tests, and hardcoded configuration. Our clients come to us after experiencing these problems.
IRPR follows a strict engineering playbook. Every project includes error tracking with Sentry, logging with Winston, and monitoring with Datadog. We write unit tests with Jest and integration tests with Supertest.
- No automated tests
- Hardcoded config values
- No error tracking
- No CI/CD pipeline
- Inconsistent code style
- No documentation
- 100% test coverage on critical paths
- Environment variables via dotenv
- Sentry error tracking on day 1
- GitHub Actions CI/CD from sprint 1
- TypeScript with strict mode
- OpenAPI docs for every endpoint
Our Node.js Development Process: From Idea to Production
We follow a 4-phase process that guarantees clarity, speed, and quality.
Phase 1 (Idea) takes 1-2 days. We review your requirements and create a high-level architecture document. Phase 2 (Roadmap) takes 1 week. We deliver a fixed-price proposal with a detailed sprint plan and tech stack decisions.
Phase 3 (Product) is the main build phase. We work in 2-week sprints with demos every 2 weeks. You see working code from sprint 1. Phase 4 (Release) includes deployment, load testing, and a 30-day warranty.
What Ships with Every Node.js Project
Every project comes with a standard set of deliverables that ensure quality, security, and maintainability.
We do not cut corners. Every Node.js project includes production-grade tooling from day one. You get full ownership of all code, documentation, and infrastructure.
Our standard delivery includes automated tests, CI/CD, error monitoring, and performance logging. We also provide a handover document that explains how to run, deploy, and maintain the application.
- Source code in your GitHub or GitLab repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- Winston logging with structured JSON output
- Jest unit tests and Supertest integration tests
- Environment variable management with dotenv
- Docker Compose for local development
- OpenAPI (Swagger) documentation for all endpoints
- Deployment scripts for AWS EC2, ECS, or Lambda
- 30-day post-launch support and bug fixes

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 exact cost before we write a line of code.
Senior Engineers Only
We do not hire juniors or outsource to low-cost regions. Every engineer on your project has 10+ years of experience and has shipped at least 5 production Node.js applications.
TypeScript by Default
We write all Node.js code in TypeScript with strict mode enabled. This catches bugs at compile time and makes the codebase easier to maintain. Our TypeScript adoption rate is 100% across all projects.
Production-Ready from Sprint 1
From the first sprint, your code runs on a real server with CI/CD, error tracking, and monitoring. You see a working demo every 2 weeks, not a mockup.
Full Code Ownership
You own all source code, documentation, and infrastructure configuration. There is no proprietary framework, no license fees, and no lock-in. We hand over everything.
30-Day Post-Launch Warranty
After deployment, we provide 30 days of bug fixes and support at no extra cost. We monitor Sentry and Datadog to catch issues before you notice them.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
