Why choose a senior custom SaaS development agency like IRPR
Our track record speaks for itself.

Every project is delivered on time and on budget. We maintain 99.9% uptime for all production deployments, backed by AWS infrastructure.
IRPR vs generic dev shops
Not all agencies deliver senior-level work.
Generic agencies often assign junior developers and bill by the hour, leading to cost overruns and quality issues. IRPR assigns senior engineers only and works on a fixed price.
We also handle compliance from day one. HIPAA, PCI-DSS, SOC 2 — we build it in, not bolt it on after launch.
- Junior developers on your project
- Hourly billing with no cap
- No compliance expertise
- Scope creep is common
- No dedicated project manager
- Code ownership is unclear
- Senior engineers with 10+ years experience
- Fixed price from $80K
- HIPAA, PCI, SOC 2 built in
- Scope locked in Roadmap phase
- Dedicated PM and QA
