Senior React Frontend Development FirmReact Frontend Development
We build complex React frontends that ship in 8-12 weeks. Fixed price, no surprises.
IRPR is a senior react frontend development firm that builds production-grade interfaces using React, TypeScript, Next.js, and React Native. We focus on component architecture, state management with Redux or Zustand, and server-side rendering to deliver fast, maintainable frontends.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2) without slowing down. Your code is yours from day one.

Why hire a senior react frontend development firm
Junior teams cost less upfront but cost more in rework. Senior engineers ship faster and safer.
A senior React developer at IRPR has built 10+ production apps. They know when to use useMemo, how to optimize Next.js ISR, and how to set up Cypress tests without you asking. We assign 2-4 senior engineers per project, not a junior team with a lead.
Our senior-first model cuts debugging time by 40%. We use TypeScript from the start, enforce consistent code style with Prettier and ESLint, and run automated accessibility checks. Every project ships with 90%+ test coverage and a full CI/CD pipeline.
How we are different from other react development agencies
Most agencies bill hourly and change scope. We give you a fixed price and a strict timeline.
IRPR writes a detailed Roadmap in week 2. You get a fixed price, a 12-week timeline, and a list of deliverables. No scope creep, no surprise invoices, no 'we need more money for that feature.'
Our code is your code. After the project, you have full ownership, source code in your repo, and documentation to run it yourself. We set up error monitoring with Sentry, logging with Datadog, and hosting on Vercel or AWS. You can keep us for maintenance or take it in-house.

Our process for building your react frontend
We follow a 4-phase process from idea to shipping. Each phase has a fixed duration and output.
Phase 1 (Idea) takes 1 week. We review your requirements, existing designs, and technical constraints. You talk directly to the senior engineers who will build the product. No account managers.
Phase 2 (Roadmap) takes 1 week. We deliver a detailed roadmap with wireframes, tech stack decisions, and a fixed price. You approve the roadmap, and we start building. No changes after this point unless you add scope with a new quote.
What you get when you ship with us
Every project includes these deliverables by default. No add-ons, no upsells.
You own the code. We put everything in your repository from day one. You get a working CI/CD pipeline, automated tests, and a monitoring stack. No vendor lock-in.
We also include a 1-month warranty. If something breaks in production, we fix it at no extra cost. After that, we offer maintenance retainer at $5K-$15K/month depending on complexity.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline using GitHub Actions
- TypeScript throughout the codebase
- 90%+ test coverage with Jest and Cypress
- Sentry error tracking from day one
- Storybook component library for your design system
- Accessibility audit (a11y) report

Why teams hire us.
Senior engineers, not junior teams
Every IRPR engineer averages 8 years of React experience. You never get a junior who needs hand-holding. Your project is built by people who have shipped 10+ production apps.
Fixed price from day 1
We quote a fixed price in week 2 after the Roadmap phase. The price does not change unless you add scope. Over 90% of our projects finish on budget.
8-12 week delivery
Our average MVP ships in 12 weeks. We use parallel sprints and reusable component libraries to hit deadlines. 98% of our projects ship on time.
Full code ownership
Your code lives in your repo from the first commit. We use your GitHub organization, your AWS account, your Microsoft Teams. You can walk away at any point with everything you need.
Compliance built in
We have built HIPAA, PCI-DSS, SOC 2, and FERPA compliant apps. We set up encryption, audit logs, and access controls as part of the standard build, not as an add-on.
Post-launch support included
Every project includes a 30-day warranty. We fix production bugs for free. After that, you can hire us for maintenance, feature additions, or scaling. No retainer required upfront.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
