Senior Frontend App Development ServicesFrontend App
We build frontend apps with React, Next.js, and TypeScript. You get an MVP in 12 weeks with fixed pricing and full code ownership.
IRPR delivers senior frontend app development services for companies that need production-grade user interfaces. We use React, Next.js, TypeScript, Tailwind CSS, and Storybook to build fast, accessible, and maintainable frontend applications.
Every project ships with a complete UI component library, automated visual regression testing with Chromatic, and a CI/CD pipeline on Vercel or AWS. Our typical MVP timeline is 12 weeks with pricing from $80K to $250K. We support compliance standards like HIPAA, PCI-DSS, and SOC 2 for regulated industries.
Founders hire us to build investor-ready frontend MVPs. CTOs hire us to rebuild legacy UIs with modern frameworks. Product managers hire us to ship complex dashboards and data-heavy interfaces. Each engagement gives them a senior frontend team without the overhead of hiring.

Senior frontend app development services by the numbers
Our track record shows what senior frontend engineers can deliver.
IRPR has shipped over 200 frontend applications across 50 countries. Our senior engineers average 10+ years of experience with React, Next.js, and TypeScript. We deliver 98% of projects on time and on budget.
Every frontend we build goes through automated accessibility audits, Lighthouse performance scoring, and visual regression testing. Our average Lighthouse performance score across all shipped projects is 92+. We maintain 99.9% uptime on hosted frontend applications.
Generic dev shop vs senior frontend team
Not all frontend development services are the same. Here is what sets IRPR apart.
Generic dev shops assign junior developers who learn on your project. They use outdated patterns, skip testing, and deliver code that is hard to maintain. You pay hourly and watch the budget grow without clear milestones.
IRPR assigns senior frontend engineers with deep experience in React, Next.js, and TypeScript. We write tests from day one, use component-driven development, and deliver a complete UI library. You get a fixed price, a clear timeline, and full code ownership.
- Junior developers with 1-2 years experience
- No automated testing or visual regression
- Hourly billing with no cap
- No design system or reusable components
- Poor accessibility and slow load times
- No post-launch support or documentation
- Senior engineers with 10+ years average experience
- Automated testing with Jest, Cypress, and Chromatic
- Fixed price from $80K with clear milestones
- Reusable component library in Storybook
- Accessible (WCAG 2.1 AA) and fast (Lighthouse 90+)
- Post-launch support and full documentation
Our frontend development process in 4 phases
We follow a structured process to ship senior-grade frontend apps on time.
Every project starts with a 2-week Roadmap phase where we define the UI architecture, component tree, and data flow. This phase costs $8K and produces a fixed-price proposal.
After approval, we build the frontend in 2-week sprints with continuous deployment. You see working code every sprint and give feedback. We handle hosting, CI/CD, and automated testing as part of the package.
What ships with every frontend app
Every project includes these deliverables by default.
We do not hand over a zip file and walk away. Every engagement includes a production-ready frontend with all the tooling and documentation you need to maintain and scale it.
You get the source code in your own GitHub repository, a CI/CD pipeline, automated tests, and a component library. We also provide a deployment guide and a handoff session with your team.
- Source code in your private GitHub repo
- CI/CD pipeline on Vercel or AWS Amplify
- Automated unit tests with Jest and React Testing Library
- Visual regression tests with Chromatic
- Accessibility audit report with axe-core
- Lighthouse performance report (target 90+)
- Storybook component library with all UI components
- Deployment guide and runbook
- Post-launch support for 30 days
- Full code ownership with no licensing fees

Why teams hire us.
Senior engineers only, no juniors

Fixed price from $80K
We give you a fixed price after the 2-week Roadmap phase. No hourly billing, no surprise invoices. The price covers the full frontend build including testing, deployment, and documentation.
12-week MVP delivery
Most frontend MVPs ship in 12 weeks. We use 2-week sprints with continuous deployment so you see working code every sprint. 98% of our projects deliver on time.
Full code ownership
You own every line of code we write. No licensing fees, no lock-in. The source code, component library, and documentation are all yours in your own GitHub repository.

Accessible and compliant by default
Every frontend meets WCAG 2.1 AA accessibility standards. We support HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries. Automated accessibility audits run in every pull request.
