Why hire expert Node.js app development consultants
Node.js powers over 30 million websites and is the runtime of choice for high-throughput applications.
IRPR has shipped 200+ Node.js applications across 50 countries. Our consultants average 10+ years of experience and hold certifications in AWS, Kubernetes, and Node.js. We deliver production-ready code within 8-12 weeks.
Every project includes automated testing with Jest, load testing with k6, and monitoring with Sentry. We deploy on infrastructure that handles 10,000+ requests per second without breaking.
How IRPR differs from other Node.js agencies
Most agencies bill hourly and deliver late. IRPR fixes pricing and timeline upfront.
Generic dev shops often start coding without a clear roadmap. They use junior developers and bill by the hour, leading to cost overruns and missed deadlines. Code quality suffers, and you own nothing.
IRPR assigns senior engineers only. We produce a detailed roadmap in week 2, lock the price, and ship the full product by week 12. You own all code, documentation, and deployment scripts.
- hourly billing with no cap
- junior developers on your project
- no roadmap before coding
- code not documented
- no CI/CD pipeline included
- you do not own the code by default
- fixed price from day one
- senior engineers with 10+ years
- detailed roadmap in week 2
- full documentation and tests
- CI/CD pipeline on GitHub Actions
- you own everything, always
Our Node.js consulting process
We follow a four-phase process from idea to release, with clear milestones at each step.
The process starts with a 1-week discovery sprint. We map your requirements, identify risks, and propose a tech stack. Then we build a detailed roadmap with wireframes and database schema.
Development happens in 2-week sprints with daily standups and weekly demos. Testing and deployment are automated from sprint 1. Release includes monitoring, documentation, and a 30-day warranty.
What ships with every Node.js project
You are not just buying code. You get a complete, production-ready system.
Every project includes source code in your private GitHub repo, full CI/CD pipeline with automated tests, and deployment scripts for AWS or your own servers. We also provide API documentation with Swagger and a Postman collection.
Monitoring with Sentry and Datadog is set up from day one. You get a runbook for common operations and a 30-day warranty for any bugs. No hidden fees, no ongoing obligations.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests with Jest
- API documentation via Swagger/OpenAPI
- Postman collection for testing
- Deployment scripts for AWS ECS or Lambda
- Sentry error tracking and alerts
- Datadog monitoring dashboard
- Operations runbook for common tasks
- 30-day post-launch warranty

Why teams hire us.
Senior engineers only
Every consultant has 10+ years of Node.js experience. We do not staff juniors or offshore teams. Your project gets a lead engineer who has shipped production systems at scale.
Fixed price, not hourly
We quote a fixed price 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.
8-12 week delivery
Our process is optimized for speed. Most MVPs ship in 8-12 weeks. We have a 98% on-time delivery rate across 200+ projects. You get a working product fast.
Full code ownership
You own all source code, documentation, and deployment scripts. There is no locked-in license or recurring fee. Take the code to any team after we finish.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant systems from the start. Our team has passed audits for healthcare, fintech, and enterprise clients. No retrofitting required.
Production-grade monitoring
Every project ships with Sentry error tracking and Datadog performance monitoring. We set up alerts for downtime and errors. You see what is happening in real time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
