Why hire a senior frontend app development vendor
A senior frontend app development vendor brings deep expertise in architecture, performance, and maintainability.
IRPR has shipped 200+ frontend apps across 50 countries. Our engineers average 10+ years of experience. We use React, Vue, Next.js, and TypeScript on every project. We also handle testing with Jest, Cypress, and Playwright to catch bugs before they reach production.
We build for scale from day one. Code splitting, lazy loading, and CDN caching are standard. We set up Sentry error tracking and Datadog RUM for real-user monitoring. Every app ships with a Lighthouse score above 85.
Generic dev shop vs senior frontend app development vendor
Not every agency delivers senior-level frontend work. Here is the difference.
Generic dev shops often assign junior developers to frontend tasks. They use outdated libraries, skip testing, and deliver slow apps. You end up with technical debt and a rewrite within a year.
IRPR assigns senior engineers only. We write clean, typed code with full test coverage. We set up CI/CD, error monitoring, and performance budgets. Your app is production-ready from day one.
- Junior developers with 1-2 years experience
- No TypeScript or type safety
- No automated testing
- No CI/CD pipeline
- No performance monitoring
- No code ownership guarantee
- Senior engineers with 10+ years experience
- TypeScript and strict linting enforced
- Jest, Cypress, Playwright test suites
- GitHub Actions CI/CD pipeline
- Sentry and Datadog RUM monitoring
- Full source code ownership
How we build your frontend app in 8-12 weeks
Our process is designed for speed and quality. No wasted cycles.
We start with a 2-week Roadmap phase. You get a detailed spec, wireframes, and a fixed price. No surprises. Then we build in 2-week sprints with daily standups and weekly demos.
By week 8 you have a working MVP. We deploy to staging, run load tests, and fix any issues. Final release includes source code, documentation, and a handoff session.
What ships with every frontend app
Every project includes these deliverables by default. No hidden extras.
We believe in full transparency. You own everything we build. No black boxes, no locked-in dependencies.
Our standard delivery includes source code, infrastructure as code, and monitoring. You can take the app to any team after launch.
- Source code in your private GitHub repo
- TypeScript with strict mode enabled
- Jest unit tests with 80%+ coverage
- Cypress end-to-end tests for critical flows
- CI/CD pipeline on GitHub Actions
- Sentry error tracking configured
