Node.js development at scale
IRPR has shipped over 200 Node.js applications for clients across 50 countries.
Every Node.js project at IRPR is built by senior engineers using proven patterns. We focus on performance, security, and maintainability from day one.
Our clients range from early-stage startups to Fortune 500 companies. We have delivered Node.js apps in healthcare, fintech, ecommerce, and more.
Why IRPR vs generic dev shops
Most Node.js development agencies bill hourly and miss deadlines. We do it differently.
Generic shops often assign junior developers and charge by the hour. This leads to budget overruns and inconsistent quality.
IRPR assigns senior Node.js engineers only, provides a fixed price, and guarantees delivery in 8-12 weeks. You get full code ownership and compliance expertise.

- Junior developers on your project
- No fixed timeline
- Code quality not guaranteed
- No post-launch support
- No compliance expertise
- Fixed price from the start
- Senior Node.js engineers only
- 8-12 week delivery guarantee
- Full code ownership
- 1 year of maintenance included
- HIPAA/PCI/SOC 2 expertise
Our Node.js development process
From idea to production in 8-12 weeks.
We break every project into clear phases so you always know what's happening. Each phase has specific deliverables and checkpoints.
You get weekly demos and a shared roadmap. Changes are handled through a structured change request process, not scope creep.
