Experienced Node.js Backend Development PartnerBackend Development
We build production-ready Node.js backends in 12 weeks. Fixed price, senior engineers only, no scope creep.
IRPR is an experienced Node.js backend development partner that builds server-side systems using Node.js, TypeScript, Express, NestJS, PostgreSQL, Redis, and AWS Lambda. We design RESTful APIs, GraphQL endpoints, event-driven microservices, and real-time WebSocket architectures that handle millions of requests per month.
Every engagement starts with a 2-week Roadmap phase to define scope, architecture, and a fixed price. Typical MVPs ship in 8-12 weeks with costs between $80K and $250K. We comply with HIPAA, PCI-DSS, SOC 2, and GDPR standards for healthcare, fintech, and enterprise clients.
Startups hire us to build their first scalable backend. SaaS companies hire us to migrate from monolithic to microservice architectures. Enterprise teams hire us to augment their in-house Node.js capacity with senior engineers who ship code immediately.
Types of software we ship.
RESTful API development
Build versioned REST APIs with Express or Fastify, JWT auth, rate limiting, and Swagger documentation. Integrates with Stripe, SendGrid, and Auth0.
GraphQL API development
Design GraphQL schemas with Apollo Server, resolvers, data loaders, and subscriptions. Supports federation for distributed backends.

Why choose an experienced Node.js backend development partner
IRPR has shipped 200+ production Node.js backends for companies across 50 countries.
A Node.js backend is the foundation of your entire product. If the API is slow, the database queries are unoptimized, or the deployment pipeline breaks, your users leave. IRPR assigns senior Node.js engineers who have built systems handling 1 million+ daily requests. We use TypeScript for type safety, PostgreSQL for relational data, and Redis for caching. Every project includes automated testing with Jest, load testing with k6, and 99.9% uptime SLAs.
We work as an extension of your team. You get daily standup updates, a shared Slack channel, and access to our GitHub repositories from day one. Our fixed pricing model means no surprises. The Roadmap phase (week 1-2) produces a detailed technical spec and a fixed quote. After that, we ship the backend in 8-12 weeks with full documentation and CI/CD pipelines.
How IRPR is different from other Node.js development agencies
Most agencies assign junior developers, bill by the hour, and leave you with undocumented code.
IRPR assigns senior Node.js engineers with 8+ years of experience. You get a named engineering lead who stays on your project from Roadmap to Release. No handoffs, no junior devs learning on your dime. We use a fixed price model: after the 2-week Roadmap, you know exactly what the backend will cost and when it will ship.
We write production-grade code from day one. Every repository includes ESLint configuration, Prettier formatting, Husky pre-commit hooks, and a full test suite. We deploy to AWS with Infrastructure as Code using Terraform or Pulumi. You own the source code, the Docker images, and the CI/CD pipelines. There is no vendor lock-in.
- Junior developers with 1-2 years of Node.js experience
- Hourly billing with no cap on total cost
- No technical spec before development starts
- Code without tests or documentation
- One-size-fits-all architecture (usually Express only)
- No CI/CD pipeline, manual deployments
- Senior engineers with 8+ years of Node.js experience
- Fixed price after a 2-week Roadmap phase
- Detailed technical spec with architecture diagrams
- Full test suite (Jest, Supertest, Cypress)
- Best-fit architecture: Express, NestJS, Fastify, or serverless
- Automated CI/CD with GitHub Actions and AWS ECS
Our process for building your Node.js backend
We follow a 4-phase framework: Idea, Roadmap, Product, Release.
Every project starts with the Idea phase. We review your product requirements, existing codebase if any, and technical constraints. This takes 1-2 days and is free of charge. If we both agree to proceed, we move to the Roadmap phase.
In the Roadmap phase (week 2), our lead engineer writes a detailed technical specification. It covers API endpoints, database schema, authentication strategy, deployment architecture, and testing plan. You get a fixed price and a 8-12 week timeline. After approval, we build the backend in 2-week sprints with continuous delivery.
What ships with your Node.js backend
Every project delivers a complete, production-ready backend system.
You are not just getting code. You get a fully operational backend with monitoring, error tracking, and automated deployments. Our team ensures that the system is secure, scalable, and documented. You can hand it to any internal team or deploy it yourself immediately.
All source code is in your private GitHub repository from day one. We use Husky for pre-commit hooks, ESLint for code quality, and Jest for unit tests. The deployment pipeline runs on GitHub Actions and deploys to AWS ECS Fargate. Sentry tracks errors in production, and Datadog monitors performance.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated testing and deployment
- Sentry error tracking with alerts
- Datadog monitoring dashboard for API latency and error rates
- PostgreSQL database schema with migrations (using TypeORM or Prisma)
- RESTful or GraphQL API with Swagger or Apollo Studio documentation
- Docker Compose setup for local development
- Load testing script with k6 for performance validation
- Security audit report (OWASP Top 10 checks)
- Deployment guide and runbook for your DevOps team
