React.js Development FirmDevelopment Firm
We build production-grade React.js apps for startups and enterprises. Senior React engineers deliver your MVP in 8-12 weeks with fixed pricing.
IRPR builds full-stack React.js applications for startups and established companies. We use React.js with Next.js, TypeScript, and Node.js to create fast, scalable web apps that handle real traffic and real data.
Each project ships as a production-ready product in 8 to 12 weeks. Pricing is fixed from $80,000 to $250,000 depending on scope. We handle compliance like HIPAA, SOC 2, and PCI-DSS when needed.
We work with founders who need a working MVP to raise their seed round, CTOs who want to offload React.js development to senior engineers, and product teams that need to ship a new feature under a tight deadline.

Why choose IRPR for React.js development
We have shipped 200+ React.js products and know what it takes to go from idea to production.
Every project is staffed with senior React engineers who have built applications for financial services, healthcare, and e-commerce. We use a proven 4-phase process to eliminate guesswork and keep timelines predictable.
Our pricing is fixed after a 1-week Roadmap phase. You never see an hourly bill or a surprise overage. We have delivered on time for 98% of projects, and we stand behind that number.
IRPR vs generic React.js agencies
Most agencies talk about quality but bill hourly and staff juniors. We do the opposite.
Generic dev shops often focus on hourly billing, which incentivizes slow work. They assign junior developers because seniors are expensive, and compliance is an afterthought. The result is a product that ships late, over budget, and with technical debt.
IRPR bills a fixed price based on a clear scope. Every engineer has 7+ years of experience. We build compliance into the architecture from day one. The result is a product that ships on time, on budget, and with full test coverage.
- Bills hourly, no fixed price
- Junior developers on your project
- No compliance knowledge
- Slow onboarding, 4+ weeks
- Little to no QA
- Code not documented / no handover
- Fixed price from the Roadmap phase
- Senior engineers only (7+ years experience)
- HIPAA, SOC 2, PCI-DSS built in
- Start building in 1-2 weeks
- Automated testing with Playwright
- Full source code ownership + CI/CD pipeline
How we build your React.js app
We follow a 4-phase process that turns your idea into a production-grade product with no surprises.
Every project starts with a 1-week Roadmap where we define scope, architecture, and a fixed price. You sign off before any code is written.
During development we run 2-week sprints with a demo at the end of each sprint. Automated tests (Playwright, Jest) run on every commit. The final phase is production deployment and a 30-day support period.
What ships with your React.js product
You don't just get code. You get everything needed to run, maintain, and scale your application.
Every delivery includes full source code, automated tests, deployment scripts, and monitoring. You own all of it from day one.
- Source code in your GitHub repo
- CI/CD pipeline (GitHub Actions)
- Sentry error tracking
- Automated QA suite (Playwright)
- Deployment on Vercel or AWS
- SEO metadata (Next.js)
- Responsive mobile-first design
- Admin panel with user management
- API documentation (Swagger)
- Performance budget report

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing means you know the cost upfront, and we absorb overruns.
Senior engineers only
All IRPR engineers have 7+ years of React.js experience. We never staff juniors or offshore teams on client projects.
Production-ready in 8-12 weeks
Your MVP ships with full test coverage, CI/CD, and monitoring. Average timeline from kickoff to production is 10 weeks.
Full code ownership
You own every line of code from day one. We deliver source code, documentation, and deployment scripts at no extra cost.
Built-in compliance
HIPAA, SOC 2, PCI-DSS, and FERPA are baked into our architecture. No separate audit needed after launch.
No surprises, ever
We use a 4-phase process (Idea, Roadmap, Product, Release) with weekly demos and a transparent timeline. Clients see progress in real time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
