Why IRPR is the best React.js development partner
Our track record speaks for itself. We have shipped over 200 products across 50 countries with a 98% on-time delivery rate.
We are not a body shop. Every project is staffed with senior React.js engineers who average 8+ years of experience. We use Next.js, TypeScript, and modern testing frameworks like Jest and Cypress to ensure your application is production-ready.
Our fixed-price model means you know the cost from week 2. We deliver the complete source code, CI/CD pipelines, and infrastructure-as-code. You own everything.
Generic dev shop vs IRPR as your React.js partner
Not all React.js development partners are the same. Here is how IRPR differs from the typical agency.
Generic shops often start coding without a clear scope, bill hourly, and hand over code with no testing or documentation. You get surprises at every milestone.
IRPR starts with a Roadmap phase that defines the entire scope, architecture, and timeline. We write automated tests, set up CI/CD, and hand over a deployable application with full documentation.
- Hourly billing with no fixed price
- Scope creeps without a written contract
- Junior developers on your project
- No automated testing or CI/CD
- Code ownership is unclear
- Delivery delays of 4+ months
- Fixed price starting from week 2
- Detailed Roadmap with milestones
- Senior engineers only (8+ years avg)
- Jest, Cypress, and CI/CD built in
- Full source code ownership
- 8-12 week delivery guarantee
How we partner on your React.js project
Our process is designed to remove risk and keep you in control. Here are the four phases.
We start with a discovery call to understand your product goals, users, and constraints. Within two weeks we deliver a complete Roadmap with architecture, wireframes, and a fixed price.
Then we build your application in two-week sprints with full transparency. You see working software every sprint. After final QA we deploy to your infrastructure and hand over everything.
Everything that ships with your React.js application
When you choose IRPR as your React.js development partner, you get more than code. Here is what we deliver by default.
We believe in complete transparency. Every project includes the source code in your private GitHub repo, a CI/CD pipeline with GitHub Actions, and automated tests covering critical paths.
You also get infrastructure-as-code (Terraform or Pulumi), a user-facing dashboard with Sentry error tracking and Datadog monitoring, and a handover document with runbooks.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with linting and tests
- Automated test suite with Jest and Cypress
- Infrastructure-as-code using Terraform or Pulumi
- Sentry error tracking and Datadog monitoring setup
- Storybook component documentation for design teams
- API documentation with Swagger or GraphQL schema
- Handover runbook with deploy instructions
- One year of AWS or Vercel credits (up to $1,000)
- 30 days of post-launch support
What we ship in this practice.
B2B SaaS Dashboard for a Fintech Startup
Built a multi-tenant analytics dashboard with Next.js, Chart.js, and PostgreSQL. Reduced user onboarding time by 40% and cut server costs by 60% using static generation and incremental static regeneration.
Real-Time Collaboration Tool for Remote Teams
