Why Companies Choose IRPR for Node.js Development
We ship production-grade Node.js applications with senior engineers, fixed pricing, and measurable results.
IRPR has shipped over 200 products built with Node.js, Express, NestJS, and Fastify. Our engineers average 10+ years of experience and have worked on systems handling 1 million concurrent users. Every project includes automated testing, CI/CD pipelines, and monitoring from day one.
We use a four-phase process: Idea validation in week 1, Roadmap with fixed price in week 2, Product development in weeks 3-10, and Release with deployment and documentation. Clients see a working MVP by week 8, not month 8.
How We Build Node.js Applications Differently
Most agencies promise quality but deliver scope creep and technical debt. IRPR does the opposite.
Generic Node.js shops often start coding without a clear roadmap. They bill hourly, so delays mean higher costs. They use junior developers to keep margins high. You end up with a fragile codebase and no documentation.
IRPR works differently. We start with a two-week Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed price and a timeline before any code is written. Every project is built by senior engineers only.
- Hourly billing with no cap on cost
- Junior or mid-level developers assigned
- No architecture documentation
- No automated tests or CI/CD
- Scope creep without change orders
- You own nothing until final payment
- Fixed price from week 2, no surprises
- Senior engineers only (10+ years avg)
- Full architecture docs and API specs
- Automated tests, CI/CD, Sentry monitoring
- Scope is defined in the Roadmap phase
- You own the code from day one
Our Node.js Development Process
We follow a repeatable four-phase process that de-risks your investment and delivers a working product fast.
Phase 1 (Idea) takes one week. We validate your concept, define user stories, and create wireframes. Phase 2 (Roadmap) takes one week. We produce a detailed technical specification, data model, API design, and a fixed price quote.
Phase 3 (Product) takes 6-10 weeks. Our engineers build the application in two-week sprints with demos at the end of each sprint. Phase 4 (Release) takes one week. We deploy to production, set up monitoring, and hand over documentation.
What Ships with Every Node.js Project
Every Node.js application from IRPR includes these deliverables by default.
We don't just hand over code. Every project includes production-grade infrastructure, monitoring, and documentation. You get everything you need to run and maintain the application yourself or with your team.
Our standard delivery includes a CI/CD pipeline on GitHub Actions, automated tests with Jest and Supertest, error tracking with Sentry, and performance monitoring with Datadog. The entire system is deployed on AWS ECS or Lambda.
- Source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions and Docker
- Automated tests with Jest, Supertest, and Cypress
- API documentation with Swagger or Postman
- Error tracking with Sentry
- Performance monitoring with Datadog
- Deployment on AWS ECS or Lambda with auto-scaling
- Database schema migration scripts
- Admin dashboard for data management
- One-year warranty on code quality
What we ship in this practice.
Real-Time Collaboration Platform
Built a real-time document editing platform using Node.js, Socket.IO, and Redis. Handled 50,000 concurrent users with sub-100ms latency. Reduced server costs by 40% compared to the previous Ruby-based system.
Healthcare Telemedicine API
Developed a HIPAA-compliant Node.js backend for a telemedicine startup. Integrated with Twilio for video calls and Stripe for billing. Scaled to 10,000 appointments per day within 6 months of launch.
E-commerce Order Processing Pipeline
Built a Node.js microservices pipeline using Bull queues and AWS SQS. Processes 5,000 orders per hour with 99.99% reliability. Reduced order processing time from 15 minutes to 30 seconds.
Fintech Payment Gateway
Created a PCI-DSS compliant Node.js payment gateway using Express and Stripe Connect. Supports 20+ payment methods and handles $2 million in monthly transactions. Passed PCI audit on first attempt.
IoT Fleet Management Backend
Built a Node.js backend for a fleet management platform using MQTT and MongoDB. Processes 1 million GPS data points per day. Reduced fuel costs for clients by 15% through route optimization.
SaaS Multi-Tenant Analytics Dashboard
Developed a multi-tenant Node.js backend with NestJS and PostgreSQL. Supports 500+ tenants with isolated data and custom billing plans. Achieved 99.9% uptime over 12 months.
Why teams hire us.
Senior Engineers Only
Every developer on your project has 10+ years of experience and has shipped at least 5 production Node.js applications. No juniors, no interns, no learning on your dime.
Fixed Price from Week 2
After the Roadmap phase, you get a fixed price for the entire project. No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
Production-Grade by Default
Every project ships with automated tests, CI/CD, error tracking, and monitoring. You get a system that is ready for production traffic from day one, not a prototype that needs months of hardening.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant Node.js applications. Our engineers know the requirements and implement them from the start, not as an afterthought.
Full Code Ownership
You own all source code, documentation, and infrastructure configuration from day one. No licensing fees, no vendor lock-in, no hidden costs.
8-12 Week MVPs
We ship a working MVP in 8-12 weeks, not 8-12 months. Our process is optimized for speed without sacrificing quality. You can validate your idea and iterate quickly.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
