Why choose an expert Node.js app development agency
Numbers prove our delivery over 200 projects.
Our team has shipped over 200 production Node.js applications. Each project follows a structured 4-phase process: Idea, Roadmap, Product, Release.
We maintain a 98% on-time delivery rate and 99.9% uptime post-launch. Clients include startups and Fortune 500 companies across 50 countries.
IRPR vs generic development shops
Not all agencies deliver expert Node.js development.
Generic agencies cut corners. They assign junior developers, hide costs, and deliver bloated code. We work differently.
IRPR assigns senior engineers only, locks in fixed pricing in week 2, and ships clean, maintainable code.
- Junior developers at $50/hr
- Hourly billing with no cap
- No compliance experience
- Monolithic code with no tests
- Unknown timeline extensions
- No post-launch support
- Senior Node.js engineers only
- Fixed price after 2-week Roadmap
- HIPAA, PCI, SOC 2 built in
- Microservices with CI/CD and tests
- 8-12 week delivery guarantee
- 30-day post-release support
Our 4-phase Node.js app development process
From idea to release in 8-12 weeks.
Every project follows a repeatable process that eliminates surprises. Each phase has clear deliverables and milestones.
We start by nailing down the specifications, then build iteratively, and deploy with confidence.
What ships with your Node.js app
Every engagement includes the following deliverables.
We don't just hand over code. You get a fully production-ready system with everything needed to run and maintain it.
Our checklist ensures nothing is forgotten.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Deployed on AWS ECS or Lambda with auto-scaling
- Dockerized microservices (if applicable)
- API documentation with Swagger/OpenAPI
- Unit tests with Jest (90%+ coverage)
- End-to-end tests with Cypress
- Error tracking with Sentry
- Monitoring with Datadog (uptime, latency, errors)
- One-year warranty: critical bug fixes
