How We Deliver Production‑Ready Node.js Apps
IRPR has shipped 200+ Node.js applications using a proven process that reduces risk and ensures quality.
Every project starts with a 4‑week Roadmap phase where we define the architecture, data model, API endpoints, and test plan. You get a fixed price before a single line of production code is written. This phase costs $12,000 and includes a complete technical specification.
During the Build phase, we deliver sprints every two weeks. You see a working demo after week 4 of development. Our team of senior Node.js engineers uses Git, automated tests, and code review to keep quality high. Average MVP timeline is 10 weeks with a 98% on‑time rate.
Node.js App Development: IRPR vs. Generic Dev Shops
Most agencies promise Node.js experience but deliver junior‑level code. Here is how we differ.
A generic dev shop may assign a mid‑level developer who learned Node.js last year. They quote hourly, bill for meetings, and hand over code without tests or CI/CD. You later pay extra for fixes and maintenance.
IRPR assigns only senior engineers with 7+ years of Node.js experience. We quote a fixed price for the entire project, include end‑to‑end testing, automated deployments, and performance benchmarks. You own the code, the pipeline, and the infrastructure.
- Hourly billing with no cap
- Junior or mid‑level developers
- No automated tests
- No CI/CD pipeline
- Code not documented
- Post‑launch support costs extra
- Fixed price from Roadmap phase
- Senior engineers only (7+ years)
- 100% test coverage for critical paths
- CI/CD with GitHub Actions + AWS CodePipeline
- Complete documentation and architecture diagrams
- Free support for 30 days after launch
Our Node.js App Development Process in 4 Phases
From concept to production, IRPR follows a structured workflow that keeps your project on time and on budget.
We start with a Discovery call to understand your goals, data sources, and constraints. Within 48 hours you receive a high‑level estimate and a suggested tech stack.
The Roadmap phase (weeks 1–4) produces a detailed technical specification with database schema, API routes, third‑party integrations, and a fixed price. After you approve, we begin development.
What Ships With Every Node.js App
Every project from IRPR includes the following by default — no hidden costs or add‑ons.
You are not just buying code. You are buying a production‑ready system with monitoring, security, and documentation. Everything is yours to own and modify.
- Source code in your private Git repository
- CI/CD pipeline with GitHub Actions or AWS CodePipeline
- Automated unit tests (Jest) and integration tests (Supertest)
- Sentry error tracking and performance monitoring
- Database schema and migration scripts (PostgreSQL or MongoDB)
- API documentation (Swagger or Postman collection)
- Docker container setup for local development
- Deployment scripts for AWS Elastic Beanstalk or ECS
- Load test results with Artillery or k6
- 30 days post‑launch bug fixes and support
What we ship in this practice.
SaaS Analytics Dashboard
Built a real‑time analytics dashboard for a B2B SaaS platform. Node.js backend streams event data from Kafka, processes aggregations with Redis, and serves REST APIs. Reduced page load time from 4s to under 300ms. Tech stack: Node.js, Express, Socket.IO, Redis, AWS ECS.
Healthcare Patient Portal API
Developed HIPAA‑compliant API for a telemedicine startup. Handles appointment scheduling, EHR data exchange, and video call initiation. Achieved 99.9% uptime over 12 months. Tech stack: Node.js, Fastify, PostgreSQL, Twilio, AWS, HIPAA validated.
Fintech Payment Microservice

Why teams hire us.
Senior Node.js Engineers Only
Every IRPR engineer has 7+ years of Node.js and TypeScript experience. We do not outsource or hire juniors. You get a lead engineer who has shipped production apps handling 1M+ requests per day.
Fixed Price, No Surprises
After the Roadmap phase, the price does not change — even if we discover new complexity. You know the budget before we write a single line of code. Typical projects cost $80,000–$250,000.
8–12 Week MVPs
We ship a production‑ready Node.js MVP in 8 to 12 weeks. Our average is 10 weeks with a 98% on‑time rate. You get a working app you can show investors and customers right away.
Full Code Ownership
You own everything: source code, tests, CI/CD scripts, infrastructure as code, and documentation. There are no licenses, no shared IP, and no ongoing royalties. The code is yours from day one.
Built for Compliance
We have built Node.js apps that pass HIPAA, PCI-DSS, and SOC 2 audits. Our engineers understand audit logging, data encryption, access controls, and vulnerability scanning. For healthcare and fintech clients, we include compliance documentation at no extra cost.
1‑2 Week Kickoff
After you sign the Roadmap phase agreement, we start within one week. The Discovery call to first sprint is typically under 14 days. No lengthy sales cycles or contract negotiations.
