Professional React App Development AgencyReact App
We build production-grade React apps for B2B startups and enterprises. 200+ products shipped in 12 weeks or less.
IRPR is a professional react app development agency. We build single-page apps, server-side rendered dashboards, and real-time interfaces using React 18, Next.js 14, and TypeScript. Every project starts with a 2-week Roadmap phase to define scope and fix the price.
We ship production-ready React applications in 12-14 weeks for $80,000 to $250,000. Our apps pass HIPAA, PCI-DSS, and SOC 2 compliance audits. We handle deployment on AWS with CI/CD pipelines using GitHub Actions.
Startups hire us to build their first SaaS product. Mid-market companies hire us to rebuild legacy Angular or jQuery frontends. CTOs hire us to add real-time collaboration features using WebSockets and Firebase.

Why choose IRPR as your React development agency
We have shipped over 200 React applications for clients in 50 countries.
Our React team has built apps for fintech, healthcare, ecommerce, and SaaS companies. Every project uses Next.js for server-side rendering, TypeScript for type safety, and Jest for unit testing. We deploy on AWS with auto-scaling groups and CloudFront CDN.
Our fixed-price model means you know the cost before we write a single line of code. The Roadmap phase (2 weeks, $12,000) produces a detailed specification with wireframes, API contracts, and a delivery schedule. After that, the build is fixed price.
What sets IRPR apart from other React agencies
Many agencies use hourly billing and unclear scopes. We do the opposite.
When you hire a generic React development shop, you often get junior devs, scope creep, and surprise overages. IRPR assigns a team of senior engineers exclusively to your project. No time tracking. No hourly invoices.
We also provide ongoing maintenance after launch. Our support retainer covers bug fixes, dependency updates, and performance monitoring for $4,000 per month.

- Junior developers doing the work
- No written roadmap
- You read the code changes in GitHub
- No QA process
- Project handoff with no support
- Fixed price after 2-week Roadmap
- Senior React engineers only
- Detailed spec with wireframes and API contracts
- Daily Slack updates and weekly demos
- Automated testing (Jest, Cypress, Playwright)
- 12-month support and 99.9% uptime SLA
Our process for building your React app
From idea to production in 12 weeks. Here is how we do it.
We use a four-phase process that keeps the project on schedule and on budget. Each phase has a clear deliverable and a go/no-go decision point.
You stay involved through weekly demos and a shared Notion workspace. No black boxes, no surprise delays.

Why teams hire us.
Senior engineers only
Every developer on your project has 6+ years of React experience. We do not outsource work to junior devs. Your team has a designated tech lead and an account manager.
Fixed price, not hourly
You get a fixed price quote at the end of the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The total cost is agreed before development starts.
We own the risk
Because we work on a fixed price, we are motivated to deliver fast and correctly. If something takes longer than expected, we absorb the cost. Not you.
Production readiness built in
Every app ships with error tracking via Sentry, automated tests with Jest and Cypress, and a CI/CD pipeline. We do not hand over a prototype. We hand over a production app ready for real users.
Full code ownership
The source code, designs, and infrastructure configuration all belong to you. No licensing fees. No locked-in contracts. You can take the code to any team after launch.
12-week guarantee
We have shipped 200+ apps in 12 weeks or less. Our process is repeatable and proven. If we miss the deadline, we work extra hours at no cost until the app ships.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
