Top Node.js App Development ServicesApp Development
We build production-grade Node.js apps for startups and enterprises. Fast delivery, fixed pricing, and senior engineers only.
IRPR delivers top node.js app development services using Express, Fastify, NestJS, and Socket.IO. Every project is built by senior engineers with 10+ years of experience.
We ship a production-ready Node.js MVP in 8-12 weeks with a fixed price starting at $80K. All apps meet HIPAA, PCI-DSS, or SOC 2 compliance as needed.
CTOs at funded startups hire us to build scalable APIs. Product managers at mid-market companies hire us to replace legacy backends. Non-technical founders hire us to launch their SaaS platforms.
Types of software we ship.
RESTful API development
Build stateless APIs with Express or Fastify. Includes Swagger docs and Postman collections.
GraphQL backend services
Implement Apollo Server or Mercurius for flexible, type-safe data queries. Integrates with React frontends.
Real-time app backend
Use Socket.IO or WebSockets for live chat, notifications, or collaborative editing. Handles 10K+ concurrent connections.
Microservices architecture
Decompose monoliths into Node.js microservices with message queues (RabbitMQ, Redis). Scales horizontally.

Why Node.js for your next app
Node.js is the runtime behind 1000+ companies including PayPal, Netflix, and Uber.
Node.js runs on the V8 engine, same as Chrome. It handles 10,000 concurrent requests on a single server with non-blocking I/O. That means lower latency and fewer servers compared to Python or Ruby.
IRPR uses Node.js for every backend we build. We pair it with TypeScript for type safety, PostgreSQL for data, and Redis for caching. Your API responds in under 30ms at the 95th percentile.
Generic dev shop vs IRPR
Not all Node.js development companies deliver the same result. Here is what sets IRPR apart.
Many Node.js agencies assign junior developers, use hourly billing, and skip automated testing. You pay more and get code that breaks in production.
IRPR assigns only senior Node.js engineers. We write unit tests, integration tests, and set up CI/CD within the first week. Every project has a fixed price from day one.
- Junior developers on your project
- Hourly billing with no cap
- No automated testing
- Manual deployment (SSH)
- Vague timelines (2-6 months)
- No compliance expertise
- Senior Node.js engineers only
- Fixed price from Roadmap phase
- 100% test coverage in CI
- GitHub Actions + Docker deploy
- 8-12 week firm delivery
- HIPAA, PCI, SOC 2 ready
Our Node.js development process
From idea to production in 8-12 weeks with zero surprises.
We start with a 2-day Roadmap phase where we map your system architecture, data model, and API endpoints. You get a fixed price and a detailed timeline. No discovery phase that drags on.
Then we build in 2-week sprints. You see a working app every sprint. At week 10 we run load tests and security audits. At week 12 your Node.js app is in production.
What ships with every Node.js project
You get more than code. Every project includes production infrastructure and documentation.
Many Node.js agencies hand you a zip file and walk away. IRPR delivers a complete production environment with monitoring, error tracking, and deployment scripts.
You own the source code, the Docker images, and the CI/CD pipeline. Your team can maintain it from day one.
- Source code in your private GitHub repo
- CI/CD pipeline (GitHub Actions)
- Dockerized Node.js app with Docker Compose
- API documentation (Swagger or Postman collection)
- Database schema migrations (TypeORM or Prisma)
- Sentry error tracking configured
- Datadog monitoring dashboard
- Load test report (k6)
- Security audit report
- Admin panel for non-technical users
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every Node.js project gets a fixed quote during the Roadmap phase (week 1). No hourly billing, no surprise invoices. You know the cost before we write a single line of code.
Senior engineers only
Every IRPR engineer has 10+ years of experience and a deep specialization in Node.js. No juniors, no interns. Your project is managed by a tech lead with 15+ years in production.
Compliance built in
We build Node.js apps that pass HIPAA, PCI-DSS, and SOC 2 audits. Encryption, logging, and access controls are part of the standard setup. No retrofitting compliance later.
8-12 week delivery
Your production-ready Node.js app ships in 8-12 weeks. We hit 98% of our deadlines. If we are late, we notify you early and adjust scope, not budget.
Full ownership on day one
You own the source code, all Docker images, and the entire repository. No licensing fees, no vendor lock-in. You can deploy with your own team anytime.
Post-launch support included
Every project includes 30 days of bug fixes and performance monitoring after launch. We stay on your Slack channel to handle any issues. Average response time is under 2 hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
