IRPR builds high-performance Node.js applications for companies that need reliability and speed. We use Express, NestJS, Fastify, and PostgreSQL to deliver apps that handle millions of requests per day. Every project is architected for scale from the first commit.
A professional Node.js app development project at IRPR ships in 8-12 weeks for MVPs, with pricing between $80K and $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2). Our team of senior Node.js developers has shipped 200+ products across 50 countries.
We work with CTOs who need to launch an internal tool, founders building their first SaaS product, and engineering managers who need to augment their team with senior Node.js talent. Each client gets a dedicated project manager and a fixed timeline.

What you get with professional Node.js app development from IRPR
Every project ships with production-grade infrastructure and clear deliverables.
We build each Node.js app with a stack that matches the product requirements. Common choices include Express or NestJS for the API layer, PostgreSQL or MongoDB for data, Redis for caching, and AWS or Vercel for hosting. Every app gets automated tests, CI/CD pipelines, and monitoring with Sentry and Datadog.
Our Node.js developers write code that follows best practices: async/await patterns, proper error handling, input validation, and security hardening against OWASP Top 10 vulnerabilities. We use TypeScript in every project to catch bugs at compile time. The result is a professional Node.js app that stays stable under load.
Why hire IRPR for Node.js development
Most agencies over-promise and under-deliver. We do the opposite.
Generic dev shops hand your project to junior developers who learn on your dime. They charge by the hour, bill for every meeting, and deliver code that breaks in production. Their Node.js apps lack proper error handling and often fail at 100 concurrent users.
IRPR assigns senior Node.js developers who have an average of 10 years of experience. We give you a fixed price and a fixed timeline in the Roadmap phase. Every app is load tested to handle 10,000+ concurrent users. We also include monitoring and support for 30 days after launch.
- Junior developers assigned to your project
- Hourly billing with no cap
- No load testing under 500 users
- Code with no unit tests
- No CI/CD pipeline
- No post-launch support
- Senior Node.js engineers averaging 10 years experience
- Fixed price locked in Roadmap phase
- Load tested for 10,000+ concurrent users
- 100% TypeScript with automated tests
- CI/CD on GitHub Actions
- 30 days post-launch monitoring and fixes
How we build your Node.js app in 8-12 weeks
Our process turns your idea into a working product with no surprises.
We break every Node.js app into two phases: Roadmap and Build. The Roadmap phase takes 1-2 weeks and costs $5,000. We create a detailed specification, architecture diagram, database schema, and UI mockups. You approve everything before we write a line of code.
The Build phase runs 8-12 weeks with weekly demos. You see the app grow incrementally. We deploy to a staging environment by week 3. Code is in your GitHub repo from day one. No black box development.
What ships with every Node.js app
No hidden deliverables. Everything listed here is included in the fixed price.
You own the full source code, cloud infrastructure, and all credentials. There are no licensing fees, no recurring payments to us after launch. We even write documentation for your API endpoints and deployment process.
Our Node.js developers set up monitoring and alerting from week 1. You get pinged when error rates spike or latency exceeds 500ms. All logs are searchable in Grafana. This saves your team hours of debugging in production.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- TypeScript throughout the codebase
- Sentry error tracking and alerting
- Production deployment on AWS or Vercel
- Load test report with 10,000 concurrent users
- API documentation (Swagger or Postman)
- Database schema and migration scripts
- 30 days post-launch monitoring and bug fixes
- One hour of deployment training for your team

Senior engineers only
Every Node.js developer at IRPR has at least 10 years of experience. No juniors, no offshore teams, no code monkeys. Your project is built by engineers who have shipped 200+ products.
Compliance built in
We build Node.js apps that meet HIPAA, PCI-DSS, and SOC 2 standards. We handle encryption, audit logs, and access controls. No expensive retrofits after launch.
Ship in 8-12 weeks
Our process is optimized for speed. We deliver a production-ready Node.js app in 8-12 weeks. Weekly demos keep you in the loop. No long wait times.
Full code ownership
You own every line of code, every config file, and every cloud account. We never lock you in. Take the code to another team after launch if you want.
Post-launch support included
We monitor your Node.js app for 30 days after launch. We fix any bugs, optimize slow queries, and handle edge cases. Your team gets a smooth handover.
