Why choose IRPR as your senior Node.js backend development company
We have shipped 200+ backend projects. Every one uses modern Node.js, TypeScript, and a clear architecture.
IRPR was founded by engineers who had enough of bad outsourcing. We hire only senior Node.js developers with 8+ years of experience. No juniors, no offshore ping-pong. Your backend is built in the United States by engineers who write tests, document APIs, and deploy on day one of every sprint.
Our fixed-price model means you know the cost before we write a single line of code. After the Roadmap phase (week 2), you get a non-negotiable quote. A typical Node.js backend for a SaaS platform costs $80K-$250K and ships in 8-12 weeks. We have never missed a deadline in 200+ projects.
How we differ from generic Node.js development shops
Generic shops sell hours. We sell outcomes. Every Node.js backend we build comes with tests, monitoring, and deployment pipelines.
Most Node.js agencies send you junior developers who learned Express.js from a tutorial. They bill by the hour, stretch timelines, and hand you a codebase that breaks under load. Then they charge you more to fix it.
IRPR is different. Every backend is built by a senior engineer who has shipped production Node.js systems for 8+ years. We use TypeScript, write unit and integration tests with Jest, and set up CI/CD with GitHub Actions and Sentry error tracking. You own the code from day one.
- Junior or mid-level developers
- Hourly billing with no cap
- No written architecture before coding
- No automated testing (or fake coverage)
- No monitoring or error tracking set up
- Code is a black box after handoff
- Senior engineers with 8+ years Node.js
- Fixed price after a 2-week Roadmap
- Detailed architecture document before code
- Jest tests with 90%+ coverage
- Sentry, Datadog, and health endpoints
- Full source code in your Git repo
Our process for building a senior-grade Node.js backend
From idea to production in 4 phases. You control the scope. We control the quality.
Phase 1 (Idea): We align on your product vision. You tell us what your backend needs to do. We ask the hard technical questions early. This takes 3-4 days.
Phase 2 (Roadmap): Our senior engineers write a detailed architecture document with database schema, API contract, and deployment strategy. You get a fixed price and timeline. This takes 1-2 weeks.
What ships with every Node.js backend
Every project includes the infrastructure your backend needs to operate in production from day one.
We don't just write code. We ship a complete operational package: automated tests, deployment pipelines, error tracking, performance monitoring, and documentation. Your team can pick up the codebase immediately.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (lint, test, build, deploy)
- Docker containers for local development and production
- PostgreSQL or MongoDB with migration scripts
- Redis for caching and session store
- Sentry error tracking with alerts via Slack
- Swagger/OpenAPI 3.0 documentation for every endpoint
- Screenshot of hosted staging environment (PaaS or VPS)
What we ship in this practice.
Real-time analytics backend for a SaaS startup
We built a Node.js backend that ingests 10,000 events per second using RabbitMQ, processes them with worker queues, and serves aggregated dashboards via WebSockets. The client reduced time-to-insight from 4 hours to 3 seconds. Tech stack: Node.js 20, Fastify, PostgreSQL, Redis, Socket.IO, Docker.
HIPAA-compliant patient portal backend
A telemedicine startup needed a backend that stores PHI (Protected Health Information) with audit logs. We built it using Node.js + NestJS + PostgreSQL with AES-256 encryption at rest. Passed HIPAA audit on first submission. 12-week build. Tech stack: NestJS, TypeORM, PostgreSQL, AWS Route 53, Datadog.
Payment processing microservices for a fintech
We decomposed a monolith into 6 microservices handling auth, payments (Stripe Connect), ledger, fraud detection, notifications, and reconciliation. Each service scales independently. Transaction processing time dropped from 3 seconds to 200ms. Tech stack: Node.js, Express.js, Redis, RabbitMQ, PostgreSQL, Stripe.
Multi-tenant backend for a B2B SaaS platform
The client needed a backend that handles 50 tenants with isolated data and custom feature flags. We built a multi-tenant Node.js backend with schema-per-tenant and Stripe subscription billing. Onboarded first 20 tenants in the first month. Tech stack: Node.js, Fastify, PostgreSQL, Stripe, Redis.
Ecommerce backend with real-time inventory
A dropshipping company needed a backend that syncs inventory across 8 suppliers in real time. We built a Node.js service that polls supplier APIs via queue workers and updates the DB within 30 seconds. Reduced overselling from 15% to 0.2%. Tech stack: Node.js, Express.js, MongoDB, Bull queue, Stripe.
MLS data API for a real estate platform
A PropTech startup needed a backend that normalizes MLS listings from 10 different sources into a single API. We built a Node.js data pipeline with ETL jobs, search via Elasticsearch, and a RESTful API. Grew from 5,000 to 500,000 listings in 3 months. Tech stack: Node.js, PostgreSQL, Elasticsearch, Redis, Docker.
Why teams hire us.
Every engineer has 8+ years of Node.js experience
We don't hire juniors. Every developer at IRPR has at least 8 years building production Node.js systems. They have built backends that handle 1M+ requests per day. You get a team that can ship without handholding.
Fixed price from week 2, not hourly billing
After the 2-week Roadmap, you get a firm fixed price. No hourly rates. No surprise invoices. The price covers the entire build, including changes that stay within scope. 200+ projects have been delivered on fixed price.
We build for compliance from the start
HIPAA, PCI-DSS, SOC 2, and GDPR are built into every backend. We encrypt data at rest with AES-256, log all access, and use role-based access control. Our fintech backends pass PCI audits on the first try.
Every project includes test coverage and CI/CD
We write Jest unit tests and Supertest integration tests. Minimum 90% coverage. GitHub Actions runs tests, lints code, builds Docker images, and deploys to staging. You get a production-ready pipeline on day one.
You own the code and the infrastructure
After the final deployment, we transfer the GitHub repository, AWS/Azure console access, and domain management to you. There are no licensing fees, no vendor lock-in, and no recurring maintenance contracts.
We start within 2 weeks of your decision
Most agencies have a 4-6 week backlog. IRPR starts your Roadmap within 2 weeks of signing. We schedule a kickoff call, send you a technical questionnaire, and begin architecture work. Fastest time to code in the industry.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
