Hiring a React.js Agency: The IRPR Difference
Most React.js agencies sell you junior teams and hourly billing. We do the opposite.
When you hire an experienced React.js development agency like IRPR, you get senior engineers who own the full stack. No junior devs on your project. No learning curve. Your code is production-ready, tested, and deployed to your AWS or Vercel account.
We write every project with TypeScript, automated tests, and CI/CD pipelines. You own the source code from sprint 1. No vendor lock-in, no hidden costs, no long-term commitments after launch.
- Junior developers with 1-2 years of React.js experience
- Hourly billing with no budget cap
- Offshore teams with timezone delays
- No compliance knowledge for HIPAA or PCI
- Ships code without tests or documentation
- You hand over your repo at the end with no support
- Senior React.js engineers with 10+ years average experience
- Fixed price set in week 2, no surprises
- Async-first collaboration with daily overlap hours
- HIPAA, PCI-DSS, and SOC 2 compliance baked in
- TypeScript, automated tests, CI/CD from sprint 1
- Source code in your repo from day one + 30 days post-launch support
Our React.js Development Process
Four phases from idea to deployed product in 12 weeks.
Every project at IRPR follows a fixed 4-phase process. We start with a 1-week discovery sprint to define the core scope and user flows. Then we build, test, and ship in rapid iterations. You see a working product every 2 weeks, not a slideshow.
Phase 1 (Ideation) maps your user stories and data model. Phase 2 (Roadmap) produces a fixed quote and timeline. Phase 3 (Product) builds the MVP in 6-8 sprints. Phase 4 (Release) deploys to production with monitoring and error tracking.
What Ships with Every React.js Project
Every deliverable is a working asset, not a document.
When IRPR completes your React.js project, you get more than code. You get a fully configured cloud infrastructure, automated testing, and monitoring tools. Your internal team can fork the repo and start shipping features the same day.
We include 30 days of post-launch support for bug fixes and minor tweaks. You also get a handoff call with the lead engineer to explain the architecture, deployment pipeline, and any custom logic.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- TypeScript with strict configuration
- Unit and integration tests (Jest, React Testing Library)
- Sentry error tracking and performance monitoring
- Production deployment to Vercel, AWS, or GCP
- Environment variables and secrets configured
- Post-launch support for 30 calendar days
- Architecture diagram and API documentation
- License audit report for all dependencies
