Our track record proves we deliver reliable, production-ready backends on time and budget.
With over 200 products shipped to clients in 50+ countries, IRPR has built backends for everything from real-time chat to high-frequency trading. Our Node.js developers average 10+ years experience.
We guarantee 99.9% uptime on deployed systems and hold a 98% on-time delivery rate. Every project starts with a fixed-price Roadmap phase to eliminate uncertainty.
How we differ from other Node.js backend agencies
Not all development shops operate the same. Here is how IRPR stands out.
Most agencies bill by the hour and let scope creep inflate costs. IRPR gives you a fixed price after a 2-week Roadmap, so you know the exact budget from day one.
Our developers are senior engineers with 10+ years of experience. We do not outsource to juniors or use offshore teams that struggle with communication.
- Hourly billing with no budget cap
- Junior developers learning on your dime
- No compliance expertise (HIPAA, PCI, SOC 2)
- Code quality varies; no testing standards
- Long timeline with scope creep
- You don't own the full code repo
- Fixed price from Roadmap phase, no surprises
- Senior engineers only, average 10+ years
- Built-in compliance for HIPAA, PCI-DSS, SOC 2, FERPA
- Full test suite: unit, integration, e2e with Jest and Cypress
- 8-12 week delivery with sprint-based development
- You own the source code, CI/CD pipeline, and deploy to your cloud
Our 12-week Node.js backend development process
We break every project into a clear, repeatable process that keeps delivery on track.
From the initial discovery call to the final deployment, our process is designed for speed and transparency. We use project management tools like Linear and maintain a public roadmap.
Each sprint ends with a working demo. We do not disappear for months and come back with code that does not match your vision.
What you get with every Node.js backend project
We do not just hand over code. You receive a production-ready system with full documentation and support.
Every deliverable is built to your specifications and deployed to your own cloud account. You own everything, including the IP and infrastructure.
- Complete source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Deployment to your AWS, GCP, or DigitalOcean cloud
- PostgreSQL or MongoDB database schema and migrations
- API documentation (Swagger/OpenAPI)
- Sentry error monitoring and logging
- Unit, integration, and e2e tests (Jest, Cypress)
- Dockerized development environment
- Post-launch 30-day warranty on bugs
- Technical handoff document and architecture diagrams
