Why choose IRPR as your senior custom application development vendor
We have shipped over 200 custom applications across 50 countries with a 98% on-time rate.
Every project starts with a two-week discovery phase. Your senior engineering lead will define the roadmap, tech stack, and fixed price before any coding begins. This eliminates surprises and ensures the final product matches your vision.
Our team uses a proven four-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a go/no-go decision point. This structure has helped us deliver MVPs in 12 weeks or less for companies of all sizes.
What sets a senior vendor apart from a generic dev shop
Not all custom application vendors are equal. Here is how IRPR differs from the rest.
Generic development shops often assign junior developers to your project. They use hourly billing that inflates costs. They avoid compliance work because it adds complexity.
IRPR works differently. Every engineer has a minimum of 10 years of experience. We quote fixed prices in the Roadmap phase and own the compliance burden for HIPAA, PCI, and SOC 2.
- Hourly billing with no cap
- Junior or mid-level engineers
- No compliance expertise
- Code ownership unclear
- Long onboarding (4-6 weeks)
- No fixed timeline
- Fixed price from Roadmap phase
- Senior engineers (10+ years avg)
- HIPAA, PCI, SOC 2 built in
- You own 100% of the code
- Kickoff in 1-2 weeks
- 12-week MVP delivery guarantee
How IRPR builds your custom application in 4 phases
Our framework turns your idea into a production-grade application without surprises.
Phase 1 is the Idea call - a 30-minute conversation to align on goals. Phase 2 is the Roadmap - a 2-week deep dive where we define scope, tech stack, and fixed price. You pay only for the Roadmap if you decide to proceed.
Phase 3 is Product - we build your application in 8-10 weeks with weekly demos. Phase 4 is Release - we deploy to production, set up monitoring, and hand over full ownership. A 30-day warranty covers any defects found after launch.
