Why our React.js agency delivers fast and reliably
We have shipped over 200 React applications for clients in 50+ countries.
Our process starts with a 2-week Roadmap phase where we define the architecture, pick the right tools, and lock the scope. You get a fixed price and a clear delivery timeline before we write a line of code.
During build, we work in 2-week sprints with continuous deployment. You see working software every sprint. We use Next.js for SSR, Tailwind CSS for styling, and automated tests with Cypress. Every project includes a CI/CD pipeline on GitHub Actions.
The difference between IRPR and a generic dev shop
Most React agencies charge hourly and let scope creep blow your budget.
We start every project with a fixed price determined during the Roadmap phase. That means you know the exact cost before development begins. No hourly rates, no surprise overtime invoices.
Our engineers are all senior-level with an average of 10+ years in production React. We use the same tools our clients use: Next.js, TypeScript, Zustand, React Query, and Tailwind. Every project ships with a functioning CI/CD pipeline and monitoring via Sentry.
- Hourly billing with no cap
- Junior or mid-level developers
- No architecture document upfront
- Git commits without testing
- No CI/CD or monitoring
- You own nothing after final payment
- Fixed price from Roadmap phase
- Senior engineers only (10+ yr avg)
- Architecture and tech stack documented in week 2

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team averages 10+ years of production React experience. No junior developers. Every engineer passes a technical interview focused on architecture and testing.
Full code ownership
You own 100% of the source code, IP, and designs from day one. We never license or restrict your software.
CI/CD from day one
Every project ships with a GitHub Actions pipeline that runs tests, linting, and deploys to staging automatically.
98% on-time delivery
We track every project against the agreed timeline. In the last 50 projects, only 1 was delayed, and that was due to a client-side API change.
Global remote team with overlap hours
We work with clients in 50+ countries. Our team operates across time zones with guaranteed 4-hour overlap with US business hours.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
