Senior React App Development ServicesReact App
Build with engineers who have shipped 200+ production apps. Get your MVP in 8-12 weeks with fixed pricing.
IRPR builds senior-level React applications for startups and enterprises using React 18, TypeScript, Next.js, Zustand for state management, and TanStack Query for data fetching. Every project includes automated testing with Cypress and Playwright.
We deliver MVPs in 8-12 weeks with fixed pricing from $80K to $250K depending on scope. Each build ships with a CI/CD pipeline on GitHub Actions, Sentry error tracking, and 99.9% uptime SLA on AWS or Vercel.
Three buyer personas hire us: startup founders who need a scalable MVP before fundraising, mid-market CTOs modernizing legacy jQuery or Angular UIs, and product managers outsourcing complex front-end features like real-time collaboration or data visualization.

What you get with Senior React App Development Services
Every project ships with production-grade React code written by engineers who average 8+ years of experience.
We use React 18 concurrent features, custom hooks, and strict TypeScript to prevent runtime errors before they hit production. Each component is unit tested with Jest and integration tested with Cypress.
Our build pipeline runs ESLint, Prettier, and automated accessibility checks (axe-core). We deploy on Vercel or AWS with auto-scaling and SSL termination included.
The difference between generic React shops and IRPR
Most agencies hand your project to juniors and bill by the hour. We do the opposite.
Generic shops often assign one senior on paper while the work goes to offshore juniors. You get broken code, missed deadlines, and hourly bills that never end.
IRPR gives you a fixed price from day two of the Roadmap phase. You work directly with a senior engineer who has shipped production React apps at scale.
- Junior developers write the actual code
- Hourly billing that spirals
- No TypeScript or testing standards
- MVP takes 6-9 months
- You don't own the repository
- No post-launch SLA
- Senior engineers only (average 8+ years experience)
- Fixed price quoted at week 2
- TypeScript, Jest, Cypress by default
- MVP delivered in 8-12 weeks
- You own all code and repos
- 99.9% uptime SLA included
Our 4-phase React development process
From idea to release in 8-12 weeks with clear milestones and no surprises.
We use a four-phase framework: Idea, Roadmap, Product, Release. Each phase has a concrete deliverable that moves you closer to launch.
During the Roadmap phase we define the feature set, tech stack, and fixed price. You get a detailed project plan before any code is written.

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. You know the total cost before we write a line of code.
Senior-only teams
Our engineers average 8+ years of React experience. We never outsource or use junior developers. Every line of code is written by a senior who has shipped at scale.
Full code ownership
You own all source code, documentation, and infrastructure from day one. No licensing fees, no lock-in. We transfer everything to your GitHub organization at launch.
8-12 week MVP delivery
We built a product framework that consistently delivers production-grade MVPs in 8-12 weeks. Over 200 products shipped on time with 98% on-time rate.
99.9% uptime SLA
Every deployment includes monitoring, alerting, and a 30-day support window. We back our work with a written SLA that covers uptime and response times.
Compliance built in
We have built React apps for HIPAA, PCI-DSS, SOC 2, and FERPA environments. Compliance controls are coded into the architecture, not bolted on later.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
