Why senior frontend app development developers matter
Senior engineers ship faster, write cleaner code, and avoid common pitfalls that junior teams introduce.
A senior frontend developer at IRPR has 8+ years of experience with React, Vue, or Angular. They know how to structure state management, optimize bundle size, and handle edge cases like race conditions and memory leaks. Junior developers often create spaghetti code that breaks under load.
Our senior frontend app development developers have shipped over 200 products across 50 countries. They use TypeScript by default, write unit tests with Jest and Vitest, and set up end-to-end tests with Playwright. Every pull request is reviewed by another senior engineer.
How IRPR differs from generic frontend shops
Most agencies assign junior developers and bill by the hour. IRPR does the opposite.
Generic dev shops often staff projects with one senior and three juniors. The senior writes the architecture, but the juniors implement it poorly. You end up with inconsistent code, missed deadlines, and a product that needs a rewrite within a year.
IRPR assigns a team of senior frontend app development developers only. Every engineer has 8+ years of experience. We work async-first with daily standups and weekly demos. You get a fixed price and a clear timeline before we write a single line of code.
- Junior-heavy teams with 1 senior
- Hourly billing with no cap
- No fixed timeline
- Code quality varies by developer
- No CI/CD or testing setup
- You own nothing until final payment
- All senior engineers, 8+ years each
- Fixed price from Roadmap phase
- 8-12 week delivery guarantee
- TypeScript, tests, and code reviews
- CI/CD pipeline on GitHub Actions
- Full source code ownership from day one
Our frontend development process
We follow a four-phase process that turns your idea into a production-ready frontend app.
Every project starts with a two-week Roadmap phase. We define the tech stack, architecture, component tree, and API contracts. You get a fixed price and a detailed timeline. No surprises.
Then we build the frontend in 6-10 weeks using React, Vue, or Next.js. We ship incremental demos every week. You see progress in real time. After launch, we provide 30 days of post-release support and hand over all code and documentation.
What ships with every frontend project
Every project includes these deliverables by default. No hidden costs.
We believe in full transparency. When we finish a project, you get everything you need to run and maintain the frontend yourself. No lock-in, no proprietary code, no surprises.
Our senior frontend app development developers set up CI/CD, error tracking, and performance monitoring as part of the standard package. You can deploy changes in minutes, not days.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and performance monitoring
- Unit tests with Jest and Vitest (80%+ coverage)
- End-to-end tests with Playwright for critical flows
- Storybook component library with all UI components
- Deployment scripts for AWS, Vercel, or Netlify
- Technical documentation and API integration guide
- 30 days of post-release support and bug fixes
- Full ownership of all code, designs, and IP
