Why choose a partner with 200+ products shipped
Our track record shows predictable delivery and real-world reliability.
Every project starts with a fixed-price Roadmap phase. In week 2, you get a complete spec and quote. No ambiguity, no surprises.
Our senior engineers average 10+ years of experience. Teams range from 4-8 people depending on scope. We communicate daily in Slack and sync weekly on video.
How a real custom software partner is different
Most dev shops promise quality but deliver scope creep and technical debt.
Generic agencies hand off work to juniors and charge by the hour. They hide dependencies and ship untested code.
IRPR builds with senior engineers only. We give fixed prices, full code ownership, and a production-grade CI/CD pipeline from day one.
- Hourly billing with no cap
- Junior devs on critical tasks
- No documentation
- Slow code reviews up to 3 days
- No monitoring or error tracking
- Vague timelines that slip by months
- Fixed price after roadmap
- Senior engineers only (10+ yrs avg)
- Full architectural docs
- Code reviews in under 4 hours
- Sentry + Datadog monitoring
- 8-12 week delivery on MVP
Our process for building custom software
Every engagement follows four phases. Each ends with a deliverable you can use.
Phase 1: Idea validation and roadmap. We define scope, tech stack, and timeline. You get a fixed price.
Phase 2: Design and architecture. We create wireframes, data models, and API contracts. You review and approve before any code.
