Best Node.js App Development ConsultantsApp Development
We ship production Node.js apps in 8-12 weeks. Fixed price, senior engineers only, full code ownership.
IRPR builds production-grade Node.js applications for startups and enterprises. Our senior engineers use Express, Fastify, Next.js, and NestJS with PostgreSQL, Redis, and AWS to deliver scalable backends and full-stack apps.
We ship a working MVP in 8-12 weeks with fixed pricing between $80,000 and $250,000. Every project meets compliance standards like SOC 2, HIPAA, or PCI-DSS where required.
Our clients are startup CTOs who need a reliable technical partner, product managers launching a new SaaS feature, enterprise teams modernizing legacy systems, and non-technical founders who want a built-to-spec product on time and on budget.

Why IRPR is the Best Node.js App Development Consultant
We have shipped over 200 Node.js products across 50 countries with a 98% on-time record.
Every project is staffed with senior Node.js engineers who average 10+ years of experience. We do not use junior developers or offshore teams. Our consultants have built systems handling 100k+ concurrent users for fintech and healthcare clients.
Our process starts with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed price quote before any coding begins. No surprises, no hourly logging.
Compare IRPR to a Generic Development Shop
Most agencies quote vague timelines, use junior developers, and own your code. We do the opposite.
We have seen too many projects fail because of unclear requirements, hourly billing that never ends, and code that cannot be maintained. IRPR was founded to fix those problems.
Our consultants deliver clean, well-documented Node.js code with automated tests and CI/CD from day one. You own everything.
- Hourly billing that encourages scope creep
- Junior developers learning on your project
- No fixed timeline or budget guarantee
- Code stored in the agency's repo until paid
- No testing or CI/CD setup
- You pay for meetings and overhead
- Fixed price agreed in week 2, no surprises
- Senior Node.js engineers with 10+ years
- 8-12 week timeline with weekly demos
- Source code in your GitHub from day one
- Automated tests, CI/CD, and Sentry monitoring
- No overhead, just engineering
Our 4-Phase Node.js Development Process
We move from idea to deployed product in four predictable phases — no waterfall, no endless discovery.
Each phase has a fixed duration and deliverable. You approve before we move to the next. This keeps your project on track and within budget.
We use the same process for every engagement whether you are in New York, San Francisco, or London.
What Ships With Every Node.js Project
Every deliverable includes these items — no hidden fees or missing pieces.
We believe in transparency. Every project ships with production-grade infrastructure, documentation, and ownership transferred to you.
No locked repositories, no proprietary frameworks, no vendor lock-in.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions or CircleCI
- Automated unit and integration tests (Jest, Supertest)
- API documentation generated with Swagger/OpenAPI
- Sentry error tracking and performance monitoring
- Deployment scripts for AWS, Vercel, or Docker
- One-page architecture diagram and README
- 30 days of post-launch support and bug fixes
- Database schema migrations (Knex or Prisma)
- Load testing results (k6 or Artillery)
