IRPR vs. Generic Development Shops: What Sets Us Apart
Most agencies promise React expertise but deliver spaghetti code. Here is how we differ.
Generic shops often start coding without a clear plan, bill hourly, and leave you with untested code that breaks on the first load spike. You end up paying for rewrites.
IRPR starts with a 2-week Roadmap phase that produces a detailed spec, architecture decisions, and a fixed price. We write tests, enforce lint standards, and deploy on your AWS or Vercel account.
- No upfront architecture review
- Hourly billing with scope creep
- Code lacks tests or documentation
- Unknown timeline and milestones
- No performance or security audit
- You don't own the code until final payment
- 2-week Roadmap with full spec and fixed price
- Fixed price per phase — no surprises
- Jest + Cypress tests for every component
- 8-12 week timeline with bi-weekly demos
- Sentry, Lighthouse, and security scan included
- Full source code in your repo from day one

We turn your idea into a production React application in 8-12 weeks.
From concept to deployment, we follow a repeatable process that minimizes risk and maximizes speed.
Each phase ends with a review and go/no-go decision. You always know where you stand.
