Senior Node.js App Development AgencyApp Development
We build production-ready Node.js apps in 8-12 weeks. Fixed pricing, senior engineers, zero fluff.
IRPR is a senior Node.js app development agency that builds scalable backend systems and full-stack applications. We use Node.js with TypeScript, Express, and NestJS for production-grade APIs and microservices.
Every project ships with a CI/CD pipeline, automated testing, and monitoring via Sentry. Typical timelines are 8-12 weeks for an MVP, with fixed pricing from $80K to $250K. We build for compliance: SOC 2, HIPAA, PCI-DSS, FERPA.
Startups hire us to build their core product and iterate fast. Enterprise teams hire us for high-performance backend systems and API integrations. SaaS companies hire us to rebuild legacy monoliths into scalable Node.js microservices. Ecommerce brands hire us for custom Node.js checkout and inventory systems.

Why hire a senior Node.js app development agency?
Our track record speaks for itself.
We have shipped 200+ Node.js applications across 50+ countries. Our team of senior engineers averages 10+ years of experience each.
Every project is delivered on time with a fixed price. We use Node.js 20, TypeScript, and modern tooling to ensure maintainable code.
Senior Node.js agency vs general development shops
Not all dev shops are equal. Here is the difference.
Generic shops assign junior developers and change requirements mid-project. They charge hourly and deliver incomplete code with no documentation.
IRPR assigns senior engineers only, uses fixed pricing from day one, and ships production-ready code with full documentation and CI/CD.
- Junior developers with 1-3 years experience
- Hourly billing with no cap
- No automated testing in the codebase
- No CI/CD pipeline by default
- Documentation is an afterthought
- Code ownership is unclear
- Senior engineers with 8+ years experience
- Fixed price quoted in week 1
- 100% test coverage for critical paths
- CI/CD with GitHub Actions and Sentry
- Full documentation in Notion
- You own 100% of the source code
Our Node.js app development process
We follow a 4-phase process from idea to production.
Each phase has clear deliverables and a fixed timeline. You know exactly what you get and when.
We use Agile sprints with weekly demos so you see progress every 7 days.
What ships with every Node.js application?
No surprises. Here is exactly what you get.
We deliver everything needed to run and maintain your application in production.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and performance monitoring
- Cloud infrastructure on AWS or GCP with Terraform
- One-click deployment via Render or Railway
- PostgreSQL or MongoDB database with migrations
- API documentation with Swagger or GraphQL Playground
- Unit and integration tests with Jest
- Docker containerization for local development
- Admin dashboard for basic CRUD operations
What we ship in this practice.

Created a Node.js service that aggregates financial data from 20+ bank APIs using Plaid and Yodlee. Processes 1 million transactions daily with 99.99% uptime. Stack: Node.js, NestJS, MongoDB, Kafka, AWS Lambda.
Real Estate MLS API
Built a Node.js API for a real estate platform that pulls MLS listings in real time. Integrated with Mapbox for geolocation. Reduced data refresh time from 30 minutes to 30 seconds. Stack: Node.js, Express, PostgreSQL, Redis, Mapbox.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. We only bill what we quote.
Senior engineers only, no juniors
Our team averages 10+ years of Node.js experience. We never outsource to junior developers. Every engineer has built and deployed production systems at scale.
Production-ready code from day one
We write testable, documented, and containerized code from the first commit. You get CI/CD, monitoring, and infrastructure-as-code built in. No technical debt to clean up later.
8-12 week MVPs that scale
We ship a working Node.js MVP in 8 to 12 weeks. The codebase is architected to handle growth from hundreds to millions of users without rewrites.
Full code ownership
You own all source code, documentation, and infrastructure. No lock-in, no licensing fees. We hand over everything including Dockerfiles and Terraform scripts.
Compliance-ready architecture
We build Node.js applications that meet SOC 2, HIPAA, PCI-DSS, and FERPA standards. Our architecture includes audit logging, encryption, and access controls by default.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
