Why IRPR is a top Node.js app development firm
We deliver production Node.js applications that handle real traffic and real data from day one.
Every Node.js project at IRPR starts with a two-week Roadmap phase. We audit your requirements, design the architecture, and give you a fixed price. No surprises. No scope creep. You know the cost before we write a line of code.
Our engineers have built Node.js backends for companies processing 1M API calls per day. We use Express.js, NestJS, and Fastify depending on your needs. Every project includes automated tests, CI/CD pipelines, and monitoring with Datadog.
The difference between a generic dev shop and a top Node.js firm
Most agencies promise Node.js expertise but deliver junior code. IRPR is different.
Generic dev shops assign you a junior developer who learned Node.js last month. They use boilerplate code, skip testing, and deliver a fragile backend that crashes under load. You pay hourly and watch the budget burn.
IRPR assigns senior Node.js engineers with 8+ years of experience. We write testable, type-safe code with TypeScript. Every API is documented with Swagger. We deploy on AWS with auto-scaling and 99.9% uptime SLAs.
- Junior developers with 1 year of Node.js
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No monitoring or error tracking
- Code ownership unclear
- Senior engineers with 8+ years of Node.js
- Fixed price from the Roadmap phase
- 100% test coverage on critical paths
- CI/CD with GitHub Actions and Sentry
- Datadog monitoring and PagerDuty alerts
- Full code ownership transferred to you
How we build your Node.js application in 8-12 weeks
Our process is designed for speed without cutting corners.
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline. You know exactly when you will see code and when you will deploy.
The Roadmap phase takes 2 weeks. We produce a detailed technical specification with architecture diagrams, API contracts, and a project plan. You approve it, and we start building. No ambiguity, no delays.
What ships with every Node.js project
Every delivery includes more than just code. You get a complete production system.
We do not hand over a zip file and disappear. Every Node.js project comes with infrastructure, monitoring, and documentation. You can run the system from day one without IRPR.
Our standard delivery includes a fully automated CI/CD pipeline, error tracking with Sentry, and performance monitoring with Datadog. You get a runbook and a 30-day support period.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with auto-deploy
- Sentry error tracking with alerting
- Datadog performance monitoring dashboard
- Swagger/OpenAPI documentation for all endpoints
- Docker Compose file for local development
- Terraform scripts for AWS infrastructure
- Load testing report with Artillery
- 30-day post-launch support and bug fixes
What we ship in this practice.
Real-time collaboration platform
Built a Node.js backend with Socket.io and Redis for a document collaboration tool. Supports 500 concurrent editors with sub-100ms sync latency. Reduced server costs by 40% compared to the previous Python implementation.
Payment processing API
Developed a PCI-DSS compliant payment API using Express.js and Stripe. Processes 10,000 transactions per hour with 99.99% uptime. Cut transaction failure rate from 2% to 0.1%.
Telemedicine backend
Created a HIPAA-compliant Node.js backend for a telemedicine startup. Handles video call scheduling, patient records, and insurance claims. Reduced patient onboarding time from 15 minutes to 3 minutes.
E-commerce order management
Built a headless Node.js backend with GraphQL for a fashion retailer. Manages 50,000 SKUs and 1,000 orders per hour. Improved page load time by 60% using Redis caching.
Real-time analytics dashboard
Implemented a Node.js streaming pipeline with Kafka and Socket.io for a media company. Processes 1M events per day and updates dashboards in real time. Replaced a batch system that had 24-hour latency.
IoT device management API
Developed a Node.js REST API for managing 100,000 IoT devices. Uses MQTT for device communication and PostgreSQL for data storage. Achieved 99.9% uptime over 12 months.
Why teams hire us.
Senior engineers only
Every IRPR engineer has 8+ years of Node.js experience. We do not staff juniors or outsource to low-cost regions. You get a lead engineer who owns the architecture.
Fixed price, not hourly
We give you a fixed price after the Roadmap phase. No hourly billing, no surprise invoices, no scope creep. You know the cost before we build anything.
8-12 week MVPs
We ship production-ready Node.js applications in 8-12 weeks. Our average time from kickoff to first release is 10 weeks. You can start testing with real users fast.
Compliance built in
We build Node.js applications that meet HIPAA, PCI-DSS, and SOC 2 standards. Our infrastructure uses encrypted data at rest and in transit, audit logs, and role-based access control.
Full code ownership
You own all source code, documentation, and infrastructure. No licensing fees, no vendor lock-in. You can take the code and run it anywhere after the project ends.
Post-launch support
Every project includes 30 days of post-launch support. We fix bugs, answer questions, and help you scale. After that, you can extend support monthly or annually.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
