Generic shop vs IRPR for custom application development
Most agencies sell you junior devs at senior rates. We don't.
The typical development agency staffs your project with junior developers and bills hourly. You get slow progress, incomplete docs, and expensive change orders.
IRPR assigns only engineers with 15+ years of experience and locks your price after a 1-week Roadmap phase. You get modern tech, full ownership, and predictable costs.
- Bills by the hour with no cap
- Staffs projects with junior developers
- Delivers incomplete documentation
- No post-launch support included
- Uses outdated tech stacks
- Slow to respond to change requests
- Fixed price locked after Roadmap phase
- Every project staffed with 15+ year senior engineers
- Complete source code and documentation delivered
- Includes 30-day post-launch warranty
- Uses modern stack: React, Node, AWS
- Adapts to scope changes without surprise costs
How we deliver senior custom applications
Four phases that take the risk out of development.
We start with a discovery sprint to define user stories, wireframes, and a clear scope. Then we lock the fixed price and timeline in a detailed Roadmap.
Senior engineers build in 2-week sprints, and we deploy to production with full CI/CD. You review progress on a staging environment every cycle.
What ships with every custom application
No black box. You own everything.
- Source code in your private repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking configured
- Docker containers for local development
- Automated test suite (unit + integration)
- API documentation with Swagger/OpenAPI
- Admin dashboard for user management
- Data migration scripts from legacy system
- Production infrastructure as code (Terraform)
- Post-launch support manual
