Why senior TypeScript frontend development services matter
Senior TypeScript engineers reduce bugs and speed up delivery by catching type errors at compile time.
TypeScript catches 15% of runtime errors during compilation, saving weeks of debugging. IRPR's senior engineers enforce strict type safety, use discriminated unions, and write custom type guards for complex state.
Our frontends achieve 95+ Lighthouse performance scores using code splitting, tree shaking, and lazy loading. We integrate Sentry for error tracking and Datadog for real user monitoring, ensuring 99.9% uptime on critical user flows.
How IRPR differs from generic development shops
Most agencies bill hourly and hand off junior-heavy teams. IRPR gives you senior engineers and fixed prices.
Generic shops often assign junior developers to your project to meet margins. You pay for their learning curve and get code that needs rewriting. IRPR only hires senior engineers with 8+ years of experience and verifiable TypeScript expertise.
We quote a fixed price after the Roadmap phase (week 2). No hourly billing means no surprises. If scope grows, we discuss it transparently and adjust the quote before writing code.
- Junior engineers with 1-2 years experience
- Hourly billing with no cap
- Code without TypeScript strict mode
- No CI/CD pipeline setup
- Zero documentation or Storybook
- Handoff without ownership transfer
- Senior engineers with 8+ years experience
- Fixed price after Roadmap phase
- Strict TypeScript mode with full types
- CI/CD with GitHub Actions and Sentry
- Storybook component library + docs
- Full source code ownership from day one
Our process for senior TypeScript frontend development
We follow a proven 4-phase process that starts with a clear roadmap and ends with a deployed product.
Every engagement begins with a 2-week Roadmap phase where we define architecture, component tree, API contracts, and a fixed price. You approve before we write a single line of code.
During the Product phase, we build in 2-week sprints with daily standups and weekly demos. You see real progress and can adjust priorities as we go.
What ships with every senior TypeScript frontend project
Every deliverable includes production-grade code, infrastructure, and documentation.
We don't just hand over a zip file. You get a fully configured repository with CI/CD, testing, error tracking, and a living component library. Everything is documented and ready for your team to extend.
Our standard stack includes React 18, Next.js 14, TypeScript 5, Tailwind CSS, Zustand, tRPC, Playwright for E2E tests, and Storybook for visual regression testing.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and Vercel
- Sentry error tracking and performance monitoring
- Storybook component library with all states
- Playwright end-to-end test suite
- WCAG 2.1 AA accessibility report
- TypeScript strict mode with no implicit any
- Responsive design for mobile, tablet, desktop
- API integration layer with tRPC or REST
- Deployment guide and runbook
