Why choose IRPR as your node.js app development company
We ship Node.js apps that are secure, scalable, and maintainable.
IRPR has shipped over 200 Node.js applications for clients in 50 countries. Our senior engineers use Express, Fastify, and NestJS to build backends that handle millions of requests per day. Every project includes automated testing, CI/CD, and monitoring with Sentry and Datadog.
We charge a fixed price based on the Roadmap we create in week 2. This means no hourly billing surprises. Most MVPs cost between $80K and $250K and ship in 8 to 12 weeks. You own 100% of the code and IP.
How IRPR is different from other node.js development companies
Not all Node.js agencies deliver on time and on budget.
Many Node.js development shops use junior engineers, vague timelines, and hourly billing. IRPR works differently. We assign only senior engineers with 8+ years of experience. Every project has a fixed price and a fixed timeline set during the Roadmap phase.
We also handle compliance natively. Whether you need HIPAA for healthcare or PCI-DSS for payments, our team builds the controls from day one. No audits after launch.
- Hourly billing with no cap
- Junior developers with little Node.js experience
- No compliance knowledge
- Unclear scope creep after start
- No CI/CD or monitoring setup
- You don't own the source code
- Fixed price from Roadmap phase
- Senior Node.js engineers only
- HIPAA, PCI, SOC 2 built in
- Scope locked in week 2, no creep
- CI/CD with GitHub Actions + Sentry
- Full source code ownership from day one
Our 4-phase process for Node.js app development
We break every project into four clear phases so you know what to expect.
Phase 1 is the Idea Validation call where we define your core requirements and constraints. Phase 2 is the Roadmap: we deliver a detailed plan with a fixed price and timeline, usually within 2 weeks. This costs $5K and is refunded if you proceed.
Phase 3 is Product building. Our team works in 2-week sprints with daily standups and weekly demos. Phase 4 is Release: we deploy to production, set up monitoring, and hand over full code ownership.
What ships with your Node.js app
We don't just hand you code. We ship a production-ready system.
Every Node.js app from IRPR comes with a complete DevOps setup, automated tests, and documentation. You can deploy to production on day one of handover.
We also include a 30-day warranty to fix any issues at no extra cost. After that, we offer optional maintenance contracts at $5K/month.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Automated unit and integration tests (Jest/Mocha)
- Sentry error tracking and Datadog monitoring
- Docker containers for local and production
- API documentation with Swagger/OpenAPI
- Database schema and migration scripts
- Postman collection for all endpoints

Why teams hire us.
Fixed price from day 1
We scope your project in the Roadmap phase and quote a fixed price. No hourly billing, no surprise overtime charges. That price covers the entire build.
Senior engineers only
Every IRPR engineer has 8+ years of Node.js experience. We don't use juniors or outsourced teams. Your code is written by people who have built production systems at scale.
Compliance built in
We embed HIPAA, PCI-DSS, and SOC 2 controls from the start. No bolt-on security audits. Our Node.js apps are auditable on day one.
You own the code
When the project ships, you get full ownership of the source code, database schema, and infrastructure scripts. Nothing is locked behind a license.
2-week shipping cycles
We work in 2-week sprints with a demo every Friday. You see progress every 14 days and can change priorities at the end of each sprint.
Post-launch support included
Every project includes a 30-day warranty with bug fixes at no cost. We also offer maintenance contracts at $5K/month if you want us to keep improving.
