How we differ from generic dev shops
Most agencies overpromise and underdeliver. We do the opposite.
Generic development shops often assign junior developers, bill by the hour, and deliver late. IRPR assigns senior engineers only, uses fixed pricing, and guarantees delivery in 8-12 weeks.
We also build compliance into every project from day one. HIPAA, PCI-DSS, and SOC 2 are not afterthoughts; they are part of our architecture and testing process.

Our process for scalable web app development
We follow a proven 4-phase process to de-risk your project.
Every engagement starts with a Roadmap phase where we define scope, architecture, and a fixed price. This takes two weeks and costs $5K-$10K, which is applied to the build.
After that, we build in 2-week sprints with continuous demo and feedback. You see working software every sprint and can adjust priorities without blowing the budget.
