Why Choose IRPR as Your Custom Application Development Partner
Our track record and process speak for themselves.
IRPR has shipped over 200 custom applications for clients in 50+ countries. Our senior engineers have an average of 12 years experience. We deliver on time 98% of the time because we scope, estimate, and build in fixed-price sprints.
Every project starts with a 2-week Roadmap phase where we define architecture, user stories, and a fixed quote. No surprises. No scope creep. You know the cost and timeline before we write a single line of production code.
How IRPR is Different from Generic Dev Shops
Not all custom application development partners deliver the same results.
Generic agencies often use junior developers, charge by the hour, and hand off code without documentation or CI/CD. Projects run over budget and timelines slip by months.
IRPR is the opposite. We assign senior engineers only, fix the price upfront, and deliver a fully documented, tested, and deployed application. Your team gets source code, infrastructure as code, and a written warranty.
- Junior developers on your project
- Hourly billing with unknowns
- No documentation or test coverage
- Code delivered via email or zip file
- No CI/CD pipeline
- Scope creep eats your budget
- Senior engineers only (10+ years avg)
- Fixed price from the Roadmap phase
- Full documentation and automated tests
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Fixed scope with change control process
Our Process: From Idea to Production
We follow a proven framework to build your custom application on time and on budget.
Every project goes through four distinct phases that we call Idea, Roadmap, Product, and Release. This eliminates uncertainty and ensures you get exactly what you need.
The Roadmap phase (week 2) produces a complete technical specification, wireframes, and a fixed price. We then build the MVP in 8-12 weeks. After release, we provide ongoing support and maintenance.
What Ships with Every Custom Application
You don't just get code. You get a production-ready system with everything needed to run and scale.
Every delivery includes source code, infrastructure, monitoring, and documentation. Your team can take over immediately or we continue to support.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code (Terraform, AWS CloudFormation)
- Automated tests (unit, integration, end-to-end)
- Monitoring with Sentry error tracking and Datadog metrics
- Deployment to your AWS, Azure, or GCP account
- Admin dashboard for managing users and data
- API documentation (Swagger or Postman collection)
- Database schema and migration scripts
- Written warranty covering bugs and performance
