Metrics That Matter for Premium Node.js App Development Consultants
We measure success in shipped products and compliance standards. Here are the numbers behind our Node.js consulting.

The Difference Between a Generic Dev Shop and Premium Node.js Consultants
Not every agency delivers premium work. Here is how IRPR stands apart from a typical Node.js development firm.
Many agencies bill hourly and let scope creep inflate budgets. They assign junior developers and reuse boilerplate code from past projects. Their Node.js apps often lack proper testing, CI/CD, and compliance documentation.
IRPR assigns senior engineers only, gives you a fixed price during the Roadmap phase (week 2), and ships complete Node.js applications with 95%+ test coverage, automated CI/CD, and detailed deployment runbooks.
- Hourly billing with no cap
- Junior or mid-level developers
- Reused boilerplate code
- No compliance documentation
- Minimal test coverage (< 50%)
- Scope creep drives cost up
- Fixed price from Roadmap phase
- Senior engineers only
- Custom architecture from scratch
- HIPAA/PCI/SOC2 compliance built in
- 95%+ test coverage
- CI/CD, error tracking, and uptime monitoring
How Our Premium Node.js Consultation Process Works
From idea to deploy in 8-12 weeks. Here are the four phases of every Node.js project.
Every engagement starts with a discovery sprint where we map your business logic to Node.js modules. Then we produce a roadmap with fixed price and timeline. After that, we build and test iteratively. Finally, we deploy and hand over full ownership.
We use agile with two-week sprints. You get a working integration every sprint. All code is stored in your GitHub repository from day one.
What Ships with Every Premium Node.js App Development Engagement
You get more than just code. Here is every deliverable included in our Node.js consulting package.
We ship production-ready software with all the supporting infrastructure. Every project includes continuous integration, automated deployment, and monitoring. You do not need to hire a DevOps engineer separately.
All deliverables are documented and tested. Your team can take over after we hand off without a ramp-up period.
- Source code in your private GitHub repository
- CI/CD pipeline using GitHub Actions
- Automated test suite (unit + integration) with 95%+ coverage
- API documentation (Swagger/OpenAPI 3.0)
- Deployment runbook with rollback steps
- Error tracking via Sentry with alert rules
- Uptime monitoring with PagerDuty on-call setup
- Database migrations and seed scripts
- Security audit report (dependency scanning, SAST)
- Architecture decision record (ADR) for each major choice
