Why Node.js for Your Next App
Node.js delivers fast, scalable backend services used by companies like Netflix and PayPal.
Node.js uses an event-driven, non-blocking model that handles thousands of concurrent connections with low memory usage. It is ideal for real-time apps, APIs, and microservices.
IRPR has shipped over 200 Node.js projects across 50 countries. Our engineers use the latest LTS versions and follow best practices for security and performance.
How We Build Node.js Apps Differently
Most agencies bill hourly and hand off messy code. We do the opposite.
Generic dev shops often assign junior developers, use hourly billing, and ignore compliance. You end up with code you don't own and a project that drags on.
IRPR assigns senior Node.js engineers, fixes the price upfront, and delivers compliant, documented code. You own everything from day one.
- Hourly billing with no cap
- Junior developers on your project
- No compliance knowledge
- Unclear code ownership
- Slow iterations
- No post-launch support
- Fixed price from the start
- Senior Node.js engineers only
- HIPAA, SOC 2, PCI compliant
- Full source code ownership
- 2-week sprint cycles
- Sentry monitoring included
Our Node.js Development Process
We follow a proven 4-phase approach that de-risks your investment.
Every project starts with a 1-2 week Roadmap phase where we define scope, architecture, and a fixed price. No surprises.
Then we build in 2-week sprints, deploy continuously, and hand over production-ready code with full documentation.
What Ships With Every Node.js Project
Every delivery includes the assets you need to run and maintain your app independently.
We don't just hand over code. You get a complete package with monitoring, tests, and deployment scripts.
This means you can hire any developer later without being locked into IRPR.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Dockerized development environment
- Sentry error tracking
- Automated test suite (unit + integration)
- API documentation (Swagger/OpenAPI)
- Deployment playbook
- Post-launch support for 30 days
- Performance benchmarks report
- Compliance documentation (if applicable)
What we ship in this practice.
Real-Time Inventory Dashboard for Logistics
Built a Node.js WebSocket server that updates inventory levels across 10 warehouses in real time. Reduced manual data entry by 8 hours per week. Tech stack: Node.js, Socket.io, Redis, PostgreSQL.
HIPAA-Compliant Patient Portal
Developed a secure patient portal with appointment scheduling and medical record access. Achieved HIPAA compliance and passed a third-party audit. Tech stack: Node.js, Express, MongoDB, AWS Cognito.
Multi-Tenant SaaS Backend
Created a multi-tenant Node.js backend for a B2B SaaS platform. Supports 500+ tenants with isolated data and custom domains. Tech stack: Node.js, NestJS, PostgreSQL, Stripe.
E-commerce Checkout Microservice
Replaced a monolithic checkout with a Node.js microservice handling payments and order validation. Reduced checkout failure rate by 40%. Tech stack: Node.js, Express, Stripe, RabbitMQ.
Real-Time Collaboration Platform
Built a collaborative document editor with operational transforms. Supports 50 concurrent users per document with sub-second sync. Tech stack: Node.js, Socket.io, MongoDB, Redis.
Serverless Data Pipeline
Designed a serverless pipeline using AWS Lambda and Node.js to process 1 million events per day. Cut infrastructure costs by 60%. Tech stack: Node.js, AWS Lambda, DynamoDB, SQS.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior Engineers Only
We hire only senior Node.js engineers with 8+ years of experience. No juniors, no offshore teams, no rotating staff.
Compliance Built In
Our Node.js apps are built to meet HIPAA, SOC 2, and PCI-DSS standards from day one. We document every control and pass audits.
Full Code Ownership
You own all source code, documentation, and IP. There are no licensing fees, no lock-in, and no recurring royalties.
2-Week Sprints
We deliver working software every 2 weeks. You see progress, give feedback, and adjust priorities throughout the project.
Post-Launch Monitoring
Every project includes Sentry error tracking and uptime monitoring. We stay on for 30 days after launch to handle any issues.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
