Senior Node.js App Development ServicesNode.js Development
Build production-grade Node.js apps with senior engineers. We deliver your MVP in 8-12 weeks, fixed price.
IRPR builds senior Node.js app development services for teams that need production-grade backend infrastructure. We use Node.js with Express, NestJS, and TypeScript to build REST APIs, microservices, and real-time applications.
Every project ships in 8-12 weeks with a fixed price ranging from $80K to $250K. Our engineers have built 200+ products across finance, healthcare, and SaaS, meeting compliance like SOC 2 and HIPAA.
We are hired by CTOs needing a senior Node.js backend for their SaaS MVP, product managers scaling an API to handle 10K+ requests per minute, and founders launching a real-time platform with WebSockets.

Why Senior Node.js Developers Matter
A junior developer can cost you weeks of debugging. Senior engineers ship clean, scalable code.
Senior Node.js developers understand async patterns, error handling, and security pitfalls. They write unit tests, set up CI/CD, and use TypeScript to catch bugs at compile time. At IRPR, every engineer has shipped at least 5 production apps in Node.js.
Our team averages 10+ years of experience. We use Node.js with Express, NestJS, and Fastify depending on the use case. We also integrate with databases like PostgreSQL and MongoDB, message queues like RabbitMQ, and cloud providers like AWS.
Generic Agency vs Senior Node.js Team
Not all Node.js developers are equal. Here is what you avoid with a generic shop.
A generic agency assigns junior developers to your project. They use outdated patterns, skip testing, and produce code that breaks under load. You end up paying for rewrites and lost time.
IRPR assigns only senior Node.js engineers with a proven track record. We write TypeScript, set up automated testing, and design for scale from day one. Every project has a fixed price and a clear timeline.
- Assigns junior developers with Node.js experience
- No TypeScript or testing standards
- Hourly billing with unlimited scope
- No scalability planning
- Rebuilds after production issues
- No ownership of code quality
- Senior Node.js engineers with 10+ years
- TypeScript, Jest, and CI/CD from day one
- Fixed price with clear Roadmap phase
- Scale design: microservices, caching, queues
- Zero-downtime deployments
- Full code ownership and documentation
Our Node.js Development Process
We follow a proven 4-phase approach to ship your Node.js app on time.
Phase 1: Discovery and architecture planning. We analyze your requirements and choose the right framework. Phase 2: Roadmap and fixed-price quote within 2 weeks. Phase 3: Build your MVP with weekly demos and continuous deployment. Phase 4: Release to production with monitoring and post-launch support.
What Ships With Every Node.js Project
You get more than code. Every project includes these deliverables.
From day one, we set up a production-grade environment. You get a GitHub repository with full git history, a CI/CD pipeline, automated tests, and infrastructure as code.
- Source code in your GitHub repo
- CI/CD pipeline using GitHub Actions
- Automated unit tests (Jest) with 80%+ coverage
- Docker containers for reproducible builds
- API documentation (Swagger/OpenAPI)
- Deployment scripts for AWS or GCP
- Sentry error monitoring and logging
- Post-launch support for 30 days
- Architecture decision records (ADRs)
- Security audit (OWASP top 10)
What we ship in this practice.
Real-Time Chat Platform for SaaS
Built a Node.js chat backend using Socket.io and Redis. Handles 50K concurrent connections with 50ms latency. Reduced customer support tickets by 40%.
Fintech Payment Processing API
Developed a PCI-DSS compliant payment gateway using Node.js and Stripe. Processes 10K transactions per hour with idempotency keys and retry logic.
Healthcare Telemedicine App Backend
Built HIPAA-compliant Node.js backend with video call scheduling, secure messaging, and EHR integration. Reduced patient wait time by 60%.
Ecommerce Order Management System
Created a scalable order processing API with Node.js, PostgreSQL, and RabbitMQ. Handles 5K orders per day with real-time inventory updates.
Media Content Streaming Backend
Developed a Node.js backend for video on demand using HLS streaming and AWS S3. Serves 1M+ views per month with 99.9% uptime.

Why teams hire us.
Senior Engineers Only
Every engineer has 10+ years of experience and has shipped at least 5 production Node.js apps. No junior assignments, no learning on your dime.
Fixed Price, Not Hourly
We quote a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
8-12 Week MVPs
We ship a production-ready MVP in 8-12 weeks. Our record is 6 weeks for a Node.js API with authentication and payment integration.
