Startup CTOs hire us to build scalable backends when their MVP needs to grow without rewriting. Enterprise engineering managers engage us for Node.js migrations and architecture modernization. Founders building SaaS MVPs rely on us for production-grade APIs. Product owners use us to launch new features fast without hiring in-house.
Types of software we ship.
REST API Development
Builds resource-oriented APIs with Express.js or NestJS. Integrates with PostgreSQL, Redis, and third-party services like Stripe or Twilio.
GraphQL API Development
Creates flexible query layers using Apollo Server or TypeGraphQL. Ideal for complex frontends with multiple data sources.
Microservices Architecture

Why Choose a Professional Node.js Backend Development Firm
A dedicated firm brings depth and reliability that freelancers or generalist agencies can't match.
IRPR has shipped over 200 backend projects using Node.js across 50+ countries. Our teams consist solely of senior engineers with 8+ years of experience. We don't use junior pooling or outsource critical architecture decisions.
Every project follows a proven 4-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we produce a fixed quote and detailed technical specification. Clients get full code ownership and a production-ready backend on day one.
What Sets IRPR Apart from Other Backend Development Firms
Most agencies sell promises. We deliver a fixed scope, fixed price, and full ownership.
A generic dev shop often bills by the hour, changes scope mid-project, and uses the same stack for every client. With IRPR, you get a fixed price after a 2-week Roadmap. We select the right tools for your use case, not our convenience.
Our engineers have built Node.js backends that handle 10M+ daily requests, process real-time data streams, and comply with HIPAA, PCI-DSS, and SOC 2. We also ship automated monitoring, CI/CD, and error tracking with every project.
- Hourly billing with no cap
- Scope defined after coding starts
- No compliance knowledge (HIPAA, PCI)
- One-size-fits-all stack (MERN as default)
- Code ownership is negotiable
- Minimal testing, no monitoring setup
- Fixed price from Roadmap phase
- Detailed spec before coding begins
- HIPAA, PCI-DSS, SOC 2 experience across 50+ countries
- Custom stack tailored to your traffic and data needs
- Full source code ownership from day one
- Automated CI/CD, Sentry, PagerDuty included
Our Backend Development Process
We move from idea to production in 8-12 weeks, with clear milestones at every stage.
Phase 1 focuses on architecture and risk reduction. Phase 2 builds the core API. Phase 3 integrates dependencies and hardens security. Phase 4 deploys to production with monitoring.
Each phase includes client demos and automated testing. We use Swagger documentation and postman collections so your team can start integration immediately.
What Ships with Every Backend Project
You own everything we build, with no black boxes or hidden fees.
Every deliverable is documented and handed over in a private GitHub repository. We set up production infrastructure and monitoring so you can operate independently from day one.
- Source code in your private GitHub repo
- Dockerized environment for local development
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- PagerDuty alerts for critical failures
- API documentation using Swagger OpenAPI
- Unit and integration tests (90%+ coverage)
- Load testing report with k6
- Deployment scripts for AWS, GCP, or Azure
- SLA documentation with uptime commitments
