How IRPR Compares to Other Agencies
Most agencies overpromise and underdeliver. IRPR does the opposite.
We see projects fail when requirements are vague, billing is hourly, and juniors are assigned. IRPR fixes all three.
Our Roadmap phase locks in scope and price. Then our senior engineers build your app in 8-12 weeks.
- Unclear requirements
- Hourly billing surprises
- Junior developers on your project
- Monthly status reports
- No ownership of code
- Scope creep kills timeline
- Fixed price from Roadmap phase
- Senior engineers only (10+ years avg)
- You own all source code
- Weekly demo deliveries
- CI/CD pipeline from day one
- Scope is locked in week 2
Our Process for Building Custom Web Apps
Four phases get you from idea to production in 8-12 weeks.
We start with discovery to understand your users and goals. Then we create a detailed Roadmap with mockups and estimates.
Development runs in two-week sprints with continuous deployment. The final phase is load testing and go-live support.
