What a Senior Custom Application Development Firm Delivers
When you hire IRPR, you get a complete software product built by senior engineers with decades of cumulative experience.
We have shipped over 200 products across 50+ countries. Our average project timeline is 12 weeks, and 98% of projects deliver on time. Every application is built with automated CI/CD, monitoring, and security scanning from day one.

Why IRPR is Not a Generic Dev Shop
Most development firms bill by the hour and change scope. IRPR does the opposite.
Generic dev shops rely on junior developers, hourly billing, and vague deadlines. They often miss compliance requirements like HIPAA or PCI-DSS, forcing you to rebuild later. Their code rarely comes with CI/CD or monitoring.
IRPR assigns only senior engineers (10+ years average). We give you a fixed price in week 2 during the Roadmap phase. Every project ships with full source code, automated testing, and a CI/CD pipeline on GitHub Actions.
- Hourly billing, no cost guarantee
- Junior developers with high turnover
- No compliance expertise (HIPAA, PCI-DSS)
- Unclear timelines, delays common
- Code owned by the agency
- No post-launch monitoring or support
- Fixed price, no surprises
- Senior engineers only (10+ years)
- Built-in HIPAA, PCI-DSS, SOC 2
- 8-12 week delivery, 98% on-time
- You own 100% of the code
- Sentry monitoring & 99.9% uptime SLA
Our 4-Phase Delivery Process
Every senior custom application development project at IRPR follows a proven 4-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We define your user stories, flow diagrams, and technical constraints. No code is written yet, but the scope is clear.
Phase 2 (Roadmap) takes 1 week. We produce a detailed specification, UX wireframes, and a fixed price quote. You approve before we start building.
What Ships With Every Senior Custom Application Development Project
Every application comes with a complete delivery package. No hidden work, no missing pieces.
You receive production-ready source code, infrastructure as code (Terraform), and a fully configured CI/CD pipeline. We also include a monitoring stack (Sentry + CloudWatch) and automated end-to-end tests.
All projects include a 30-day post-launch support window. During that time we fix bugs and handle minor changes. After that, you can extend support or hand off to your own team.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking and performance monitoring
- Automated unit, integration, and E2E tests
- Production deployment on AWS or GCP
- SSL, DNS, CDN configured (Cloudflare)
- API documentation (Swagger/OpenAPI)
- Database schema and migration scripts
