Why choose IRPR as your custom application development agency
We deliver production-ready applications on time and on budget.
IRPR has shipped over 200 custom applications for clients in 50 countries. Our average MVP timeline is 12 weeks from kickoff to deployment. We use a fixed-price model so you know the cost before we write a single line of code.
Every project includes a dedicated lead engineer, a product manager, and a QA specialist. We deploy on AWS with CI/CD pipelines, Sentry error tracking, and Datadog monitoring. Your code is always in your own GitHub repository.
How IRPR is different from other custom application development agencies
Most agencies bill hourly and change scope. We do the opposite.
Generic development shops often start with a vague estimate and then bill for every change. You end up paying for meetings, research, and rework. The final product rarely matches the initial vision.
IRPR gives you a fixed price after a 2-week Roadmap phase. We define every feature, every integration, and every milestone. If the scope changes, we adjust the price before we build. No surprises.
- Hourly billing with no cap
- Scope creep without price updates
- Junior developers on your project
- No dedicated QA or product manager
- Code stored on their servers
- No post-launch support included
- Fixed price from the start
- Scope changes trigger a revised fixed quote
- All senior engineers with 10+ years experience
- Dedicated lead engineer, PM, and QA
- Full code ownership in your GitHub
- 30 days of post-launch support included
Our process for building your custom application
From idea to release in 12 weeks with a clear roadmap.
We follow a four-phase framework: Idea, Roadmap, Product, Release. Each phase has a fixed duration and a clear deliverable. You approve each phase before we move to the next.
The Roadmap phase is a 2-week sprint where we define the architecture, tech stack, and feature list. We deliver a detailed project plan with wireframes and a fixed price. No code is written until you sign off.

You get more than just code. Every project includes production infrastructure and documentation.
We don't just hand over a repository. We set up the entire infrastructure so your application is ready to scale. Every project includes monitoring, error tracking, and a CI/CD pipeline.
You own all the code from day one. We never license or resell your intellectual property. You can deploy to any cloud provider or on-premise server.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker containers for local and production environments
- Sentry error tracking and performance monitoring
- Datadog infrastructure monitoring
- Stripe or Braintree payment integration (if applicable)
- PostgreSQL or MongoDB database with migrations
- REST or GraphQL API documentation (Swagger/Postman)
