Why premium Node.js app development matters
Your backend is the foundation of every feature your users touch.
A poorly architected Node.js app costs you in latency, scaling bills, and developer hours. IRPR builds with Express.js, Fastify, or NestJS and deploys on AWS with auto-scaling groups. Our apps handle 10K concurrent users without breaking a sweat.
We write unit tests with Jest, integration tests with Supertest, and load tests with k6. Every project ships with a CI/CD pipeline on GitHub Actions and error tracking via Sentry. You get production-ready code from day one.
The difference between IRPR and generic dev shops
Not all Node.js developers deliver the same quality.
Generic shops often assign junior developers who learn on your dime. They use hourly billing and inflate timelines. You get code that works today but breaks in production under load.
IRPR assigns senior Node.js engineers only. We give you a fixed price in the Roadmap phase (week 2). You get source code ownership, a CI/CD pipeline, and a 90-day warranty. No surprises.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No CI/CD pipeline shipped
- Unclear code ownership
- No load testing or error tracking
- 6-9 month delivery for an MVP
- Senior engineers with 8+ years Node.js experience
- Fixed price from Roadmap phase (week 2)
- CI/CD on GitHub Actions included
- Full source code ownership
- Sentry error tracking and k6 load tests
- 8-12 week delivery for an MVP
Our Node.js app development process
We follow a 4-phase framework that de-risks your project.
Phase 1 is the Idea phase. We map your business logic, user flows, and data model. You get a detailed spec and a fixed price quote.
Phase 2 is the Roadmap. We design the system architecture, choose the tech stack (Express, NestJS, or Fastify), and set up the CI/CD pipeline. You see the full plan before we write a line of code.
What ships with every Node.js project
Every deliverable includes production-grade infrastructure.
You dont just get code. You get a fully operational backend with monitoring, CI/CD, and documentation. Our checklist ensures nothing is forgotten.
We also include a Postman collection, a README with setup instructions, and a 1-hour walkthrough call for your team. You can hand off to any developer immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and alerting
- AWS or Vercel deployment with auto-scaling
- Postman API collection with example requests
- Swagger/OpenAPI documentation
- Unit tests with Jest (90%+ coverage)
- Load test results from k6
- README with setup and deployment instructions
- 90-day warranty on all code
