Why IRPR is the Best Node.js API Development Partner
We deliver production-ready Node.js APIs on time and on budget.
IRPR has shipped over 200 products, many of which are Node.js APIs serving millions of users. Our engineers average 10+ years of experience and have built APIs for fintech, healthcare, and SaaS platforms.
We use a fixed-price model that eliminates budget surprises. Every project includes a Roadmap phase (week 2) where we lock scope and price. You get a CI/CD pipeline, monitoring, and documentation included by default.
Generic Agency vs IRPR
Most dev shops bill hourly and hand off junior developers. IRPR does the opposite.
When you hire a generic dev shop for Node.js API development, you often get hourly billing, junior engineers, and no compliance expertise. Code ownership is unclear, and post-launch support is an upsell.
IRPR assigns senior engineers only, provides a fixed price from day one, and delivers full code ownership. We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default, and include 30 days of free support.
- Hourly billing, no fixed price
- Junior or offshore developers
- No compliance knowledge
- No CI/CD or monitoring
- You don't own the code
- Post-launch support costs extra
- Fixed price after Roadmap phase
- Senior engineers (10+ years avg)
- HIPAA, PCI-DSS, SOC 2 built in
- CI/CD pipeline on GitHub Actions
- You own 100% of the code
- 30 days free post-launch support
