Senior React Web Development AgencyWeb Development
We build production-ready React apps with senior engineers only. 200+ products shipped in 12 weeks or less.
IRPR builds senior-level React web applications for companies that need reliable, scalable frontends. We use React 18 with Next.js for SSR, TypeScript for type safety, and integrate with Node.js, GraphQL, or REST APIs. Every project starts with senior engineers who have shipped 10+ React apps each.
We deliver a working product in 8 to 12 weeks with a fixed price of $80,000 to $250,000 depending on complexity. All code complies with SOC 2, HIPAA, or PCI-DSS when required. You get test coverage, CI/CD pipelines, and monitoring out of the box.
Our clients include CTOs at SaaS startups who need a React frontend for their MVP, product managers building investor-ready demos, and enterprise teams migrating legacy UIs to React. We also work with founders who want a single senior team to design, build, and release their product.

Senior React Web Development Agency delivers results by the numbers
We measure what matters: shipped products, on-time delivery, and code quality.
Every React project at IRPR is tracked against milestones. Our average MVP ships in 12 weeks, and 98% of projects finish on or before the fixed deadline. We have delivered over 200 products to clients in 50+ countries, from single-page dashboards to full SaaS platforms.
Our senior engineers average 10+ years of experience. We run automated tests on every pull request and maintain 99.9% uptime across all deployed applications. When compliance is required, we build to HIPAA, PCI-DSS, and SOC 2 standards from day one.
Why IRPR is different from other React development agencies
Generic dev shops hire juniors and bill by the hour. IRPR hires only senior engineers and charges a fixed price.
Most agencies stack junior developers to cut costs, then bill hourly for every change request. That inflates timelines and budgets. We take the opposite approach: a senior engineer writes every line of React code, and you pay a fixed price agreed in week 2.
Our Roadmap phase delivers a detailed specification, architecture diagram, and fixed quote before any coding starts. There are no surprise invoices, no scope creep, and no quality gaps. We also ship the code to your own repository on day one.
- Junior developers learning React on your project
- Hourly billing that rewards slow work
- No fixed timeline or budget guarantee
- Vague requirements that change mid-sprint
- Code delivered without tests or CI/CD
- You lose access to the code after the project
- Senior engineers with 10+ years average experience
- Fixed price from the Roadmap phase (week 2)
- 8 to 12 week MVP timeline guaranteed
- Exact spec and architecture before any code is written
- Full test coverage, CI/CD pipeline, and monitoring included
- You own the code from day one in your own repository
Our process for building senior React web applications
Four phases, clear milestones, no surprises.
Every React project follows the same IRPR framework: Idea, Roadmap, Product, Release. Each phase has a defined outcome and a fixed duration. You know exactly what you will get and when.
We start with a discovery call to align on your product vision. Then we deliver a Roadmap document that includes user stories, wireframes, technology stack, and a fixed price. After you approve, we build the MVP in 8 to 12 weeks.
What ships with every senior React project
You get more than code. Every deliverable is production-ready from day one.
We do not cut corners. Every React application includes automated testing, deployment pipelines, and error tracking. This is not optional — it is part of our standard process.
When your MVP launches, it will be in the same state as a product that has been running for months. Monitoring alerts, logging, and rollback capabilities are all configured. You can start onboarding users immediately.
- Source code in your GitHub or GitLab repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Unit and integration tests with Jest and React Testing Library
- End-to-end tests with Cypress or Playwright
- Sentry error tracking and performance monitoring
- Husky and lint-staged for pre-commit checks
- Storybook component library for UI documentation
- Docker configuration for local development
- Production deployment to AWS, Vercel, or Netlify
- 30-day post-launch support and bug fixes
What we ship in this practice.
Investor-ready SaaS dashboard for a fintech startup
Built a real-time trading analytics dashboard with React, D3.js, and WebSocket feeds. The client used it to raise a $2M seed round. Reduced page load time by 60% using memoization and virtual scrolling.
Headless ecommerce storefront for a fashion brand
Developed a React storefront with Next.js, Algolia search, and Stripe. The brand saw a 35% increase in conversion rate after the launch. Server-side rendering improved SEO and mobile load times.
Patient intake portal for a telemedicine network
Created a HIPAA-compliant React app with video calls via Twilio and EHR integration via FHIR APIs. Reduced patient wait time by 40% and cut manual data entry by 8 hours per week per clinic.
Multi-tenant CRM for a real estate platform
Built a React frontend with Firebase authentication, Stripe billing, and real-time property updates. The client onboarded 500 agents in the first 3 months. Downtime < 0.1% since launch.
Live collaboration tool for an edtech company
Delivered a React app with Socket.io and CRDTs for real-time whiteboarding. Students reported a 50% increase in engagement. The platform handled 10,000 concurrent users during peak hours.
Content management dashboard for a media publisher
Built a custom React CMS with Cloudinary image optimization and i18n support for 4 languages. Editorial team cut publishing time from 2 hours to 30 minutes per article.
Why teams hire us.
Senior engineers only
IRPR does not hire juniors. Every developer has 10+ years of experience and has shipped at least 5 React applications. You get a senior architect, senior frontend engineer, and senior DevOps engineer on every project.
Fixed price, not hourly
You pay a single fixed price agreed in the Roadmap phase (week 2). No hourly billing, no time tracking, no surprise invoices. If the scope changes, we adjust the price only after you approve.
Production-ready in 12 weeks
Most agencies deliver wireframes. IRPR delivers a deployed, tested, monitored application in 8 to 12 weeks. Your MVP includes CI/CD, error tracking, and rollback capabilities — it is ready for real users.
Full code ownership from day one
You own all code, designs, and documentation from the first commit. The code lives in your own GitHub or GitLab repository. There is no lock-in and no license fees.
Built to compliance standards
When your React app must comply with HIPAA, PCI-DSS, or SOC 2, we build it from the start. Our processes include automated security scanning, audit logging, and data encryption at rest and in transit.
Proven track record with real metrics
We have shipped over 200 products across 50+ countries, with a 98% on-time delivery rate. Our clients range from early-stage startups to publicly traded companies. Every project includes references you can call.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
