Expert Node.js App Development ServicesApp Development
We build production-ready Node.js apps in 8-12 weeks. Fixed pricing, senior engineers, zero fluff.
IRPR builds expert Node.js applications using Express, NestJS, and TypeScript for scalable server-side logic. We containerize with Docker and deploy on AWS with CI/CD pipelines for zero-downtime releases.
Every project ships with a fixed price after a 2-week Roadmap phase. Typical budgets run from $80,000 to $250,000 for an MVP in 8-12 weeks. We handle SOC 2, HIPAA, and PCI-DSS compliance when needed.
Our clients are CTOs at Series A startups who need a production-grade API in under 3 months, product managers building a SaaS MVP with multi-tenant architecture, and enterprise teams modernizing legacy systems into microservices.
Types of software we ship.
REST API Backend
Stateless JSON APIs with JWT authentication, rate limiting, and Swagger documentation. Built with Express and PostgreSQL.
GraphQL API Gateway

Why Expert Node.js App Development Matters
Node.js handles 1M+ concurrent connections per server when architected correctly.
We use Node.js for its event-driven, non-blocking I/O model. That means your app stays responsive under heavy load without adding hardware. Our teams have shipped 200+ products across 50 countries using this runtime.
A well-built Node.js backend reduces latency by 40-60% compared to legacy frameworks. We leverage clustering, worker threads, and CDN caching to keep response times under 50ms at the 99th percentile.
The Difference Between Generic Shops and IRPR
Most agencies overpromise and underdeliver. IRPR fixes that with process and senior talent.
We only assign engineers with 10+ years of experience. No juniors, no ramping up on your dime. Our fixed-price model means you know the cost before we write a line of code.
Every project starts with a 2-week Roadmap phase. You get a detailed technical specification, a fixed price, and a delivery timeline. No surprises.
- Hourly billing with no cap
- Junior developers assigned
- No compliance experience
- Unclear ownership terms
- Delayed delivery by 2-3x
- Single point of failure
- Fixed price after Roadmap
- Senior engineers only (10+ years)
- Built-in HIPAA, SOC 2, PCI-DSS
- Full code ownership
- 98% on-time delivery
- Redundant architecture with failover
Our Node.js Development Process
We deliver working software every 2 weeks with transparent reporting.
The process is designed to eliminate guesswork. Each phase ends with a tangible deliverable you can test and approve.
From Roadmap to Release, you always know what ships and when. Stakeholder demos happen bi-weekly via Zoom.
What Ships With Your Node.js App
You get more than code. Every delivery includes the full operational stack.
We believe in shipping production-ready systems, not prototypes. Every project includes the items below by default.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker containers for reproducible builds
- Automated unit and integration tests (Jest, Supertest)
- API documentation via Swagger/OpenAPI
- Sentry error tracking and performance monitoring
- Datadog dashboards for CPU, memory, and request latency
- Deployment scripts for AWS ECS or Kubernetes
- Post-launch support for 30 days (Slack + scheduled calls)
- Architecture diagram and runbook documentation
What we ship in this practice.
SaaS Subscription API

Real Estate MLS Aggregator
Built an API that aggregated property listings from 50+ MLS feeds into a single GraphQL endpoint. Reduced data refresh time from 24 hours to 15 minutes. Tech: Node.js, Apollo Server, PostgreSQL, Redis.
E-commerce Checkout Service
Replaced a legacy checkout system with a PCI-DSS compliant microservice. Handled 1,200 orders per minute during Black Friday. Reduced checkout abandonment by 18%. Tech: Node.js, Express, Stripe, Docker.
EdTech Discussion Platform
Developed a real-time discussion backend for a K-12 learning platform. Supported 50,000 concurrent posts per hour with automatic content moderation. FERPA compliant. Tech: Node.js, Socket.io, MongoDB, AWS Lambda.
Why teams hire us.
Fixed price from day one
After a 2-week Roadmap phase, we give you a fixed quote. No hourly billing, no surprise invoices. You approve the price before we start building.
Senior engineers only
Every developer on your project has 10+ years of experience. We don't staff juniors or offshore teams. You get a lead engineer who owns the architecture.
98% on-time delivery
Across 200+ products, we deliver on schedule 98% of the time. Our process uses weekly sprints and bi-weekly demos to keep every milestone visible.
Full ownership of code
You own every line of code, all documentation, and the complete deployment pipeline. No lock-in, no recurring fees. Your repo, your license.
Built-in compliance
We ship HIPAA, SOC 2, and PCI-DSS compliant Node.js apps out of the box. Our engineers configure audit logs, encryption, and access controls as standard practice.
Production monitoring included
Sentry error tracking and Datadog dashboards are included in every project. You get alerts for errors, latency spikes, and memory leaks before they affect users.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
