IRPR builds professional custom application development for companies that need reliable, scalable software. We use React, Node.js, Python, Go, and AWS to ship your product.
Every project starts with a 2-week Roadmap phase to define scope and price. Typical delivery is 8-12 weeks. Prices range from $80K to $250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance.

Why choose IRPR for professional custom application development
Our track record speaks for itself.
We have shipped over 200 custom applications across 50 countries. 98% of projects deliver on time and on budget.
Our team consists of senior engineers with an average of 10+ years experience. We focus on clean code, test coverage, and scalable architecture.
How IRPR differs from other custom development shops
Most agencies overpromise and underdeliver. We do the opposite.
We start with a paid Roadmap phase to define exactly what we build and how much it costs. No guesswork, no surprises.
Our fixed pricing means you know the budget from week 2. We don't bill hourly or chase scope creep.
- hourly billing that balloons
- unclear timelines
- junior developers assigned
- no compliance expertise
- you don't own the code
- slow communication
- fixed price from week 2
- 8-12 week delivery
- senior engineers only
- HIPAA/PCI/SOC2 built in
- full code ownership
- daily updates and async workflow
Our custom application development process
Four phases take you from idea to release.
Phase 1: Idea validation and technical scoping. In 1 week, we review your concept and provide a feasibility assessment.
Phase 2: Roadmap and fixed quote. In week 2, we deliver a detailed roadmap with milestones, tech stack, and a fixed price.
