What a senior front end development agency delivers
Every project ships with production-grade code, a design system, and a deployment pipeline.
IRPR builds front ends that users love. We use React 18, Next.js 14, TypeScript 5, and Tailwind CSS 3. Every component is tested with Cypress and Storybook. We ship with full CI/CD on GitHub Actions and error tracking with Sentry.
We write clean, maintainable code. Our engineers follow strict linting rules (ESLint, Prettier) and enforce type safety. We document every component and provide a living style guide. You get a front end that is fast, accessible, and ready for scale.
Senior front end development agency vs generic dev shop
Not all agencies deliver senior-level work. Here is the difference.
Generic dev shops assign junior developers to your project. They lack experience with state management, performance optimization, and accessibility. You end up with slow load times and technical debt.
IRPR assigns senior engineers only. Each has 7+ years of experience with React, Next.js, and TypeScript. We write performant code from the start. We ship with automated tests, responsive design, and a11y compliance.
- Junior developers with 1-2 years experience
- No dedicated QA or testing strategy
- Hourly billing with scope creep
- No design system or component library
- Slow load times and poor Lighthouse scores
- No CI/CD pipeline; manual deployments
- Senior engineers with 7+ years experience
- Automated testing with Cypress and Jest
- Fixed price from $80K, no surprises
- Custom design system in Storybook
- Lighthouse scores above 90 on every page
- Full CI/CD on GitHub Actions, auto-deploy
Our front end development process
We follow a proven 4-phase process to deliver your front end on time and on budget.
Every project starts with a 2-week discovery phase. We audit your existing code, define the tech stack, and create a detailed roadmap. You get a fixed quote before we write a single line of code.
After approval, we build in 2-week sprints. You see progress every Friday with a live demo. We handle QA, deployment, and documentation. By week 12, you have a production-ready front end.
What ships with every front end project
You get more than code. Every project includes these deliverables by default.
We believe in full transparency. From day one, you have access to the code repository, design files, and project board. No black boxes, no hidden work.
Every deliverable is production-ready. We follow industry best practices for performance, security, and maintainability. You can take the code to any other team and they will understand it.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions (build, test, deploy)
- Sentry error tracking and Datadog performance monitoring
- Design system in Storybook with all components documented
- Responsive layouts tested on mobile, tablet, and desktop
- Accessibility audit (WCAG 2.1 AA compliant)
- Lighthouse performance report (score 90+)
- Deployment to your cloud (AWS, Vercel, or Netlify)
- README with setup instructions and architecture overview
