Why the best TypeScript frontend development consultants choose modern tooling
Our consultants use TypeScript from day one to eliminate entire categories of runtime bugs.
Every IRPR project starts with strict TypeScript configs (strictNullChecks, noImplicitReturns) and a linting setup that enforces consistent code. We write typed API clients, typed Redux/Zustand stores, and typed GraphQL queries so your frontend never sees a runtime crash from mismatched data.
We combine TypeScript with React 18, Next.js 14, or Vue 3. Each project includes a component library in Storybook with auto-generated documentation. The result is a codebase that new engineers can read confidently and modify without breaking types.
Generic dev shop vs IRPR
Not every team can deliver a production-grade TypeScript frontend on time and on budget.
Many agencies treat TypeScript as an afterthought, using any types and skipping type-checking in CI. That leads to fragile code and long debugging sessions.
IRPR treats TypeScript as a first-class constraint. Every commit is type-checked, every PR has typed props and state, and every component ships with a typed story.
- Uses any types widely
- Skips TypeScript in CI pipeline
- No typed test utilities
- Mixed JavaScript/TypeScript files
- No automated type coverage reports
- Delivers late due to type-related bugs
- Strict TypeScript config from day one
- Type-checking runs on every push via GitHub Actions
- Typed testing with Vitest and Testing Library
- 100% TypeScript across the entire codebase
- Weekly type coverage reports (always above 95%)
- On-time delivery in 8-12 weeks
How we build your TypeScript frontend in 8-12 weeks
Our process is designed for speed without compromising type safety.
We start with a two-week Roadmap phase where we design the component tree, data flow, and type interfaces. You see the full architecture before we write a single component.
During the build phase we deliver working increments every two weeks. Each sprint includes typed routes, state management, and API contracts.
What ships with your TypeScript frontend
Every project includes the essentials for long-term maintainability.
We don't just hand over code. You get a complete development environment with CI/CD, error monitoring, and typed documentation.
Your team can pick up the project in one day because everything is typed and documented.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions, type-checking, and linting
- Sentry error tracking with TypeScript source maps
- Storybook component library with auto-generated docs
- Vitest unit tests with typed mocks
- Playwright end-to-end tests for critical user flows
- Lighthouse performance report (target: 90+ mobile)
- WCAG 2.1 AA accessibility audit report
- Architecture decision record (ADR) for every key choice
- One-year warranty on type coverage and build stability
What we ship in this practice.
SaaS analytics dashboard
IRPR built a real-time analytics dashboard for a B2B SaaS startup. We used React, TypeScript, and D3.js to render live charts. The client reduced time-to-insight by 60% and onboarded 3x more users in the first month.
Healthcare appointment portal
We developed a HIPAA-compliant patient portal with Next.js and TypeScript. Patients can book, reschedule, and check-in online. The clinic reduced no-shows by 25% and saved 15 hours of staff time per week.
Ecommerce storefront
For a direct-to-consumer brand, we built a Next.js storefront with Stripe payments and Algolia search. TypeScript ensured cart state never broke. Conversion rate increased by 30% and page load dropped to under 2 seconds.
Real estate listing platform
IRPR created a property search platform with React, TypeScript, and Mapbox. Users can filter by location, price, and amenities. The client reported a 40% reduction in bounce rate and 50% more leads per listing.
Fintech investment app
We built a React Native app for a robo-advisor startup. The app uses TypeScript shared types between web and mobile, plus SOC 2 compliant authentication. The client launched 4 months ahead of schedule.
EdTech learning platform
For an online course provider, we built a Vue 3 + TypeScript frontend with FERPA-compliant student data handling. The platform supports real-time quizzes and progress tracking. Student engagement rose by 35% in the first quarter.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Your budget is locked from day one.
Senior engineers only
Every consultant at IRPR has 10+ years of frontend experience and deep TypeScript expertise. You never get junior developers learning on your dollar. Our team has shipped over 200 products.
TypeScript from day one
We don't add types later. Our codebase is 100% TypeScript from the first commit. Every pull request must pass type-checking and maintain at least 95% type coverage.
No offshore handoffs
All development happens in US-friendly time zones with daily overlap. You talk directly to the senior engineer writing your code. No middlemen, no handoffs, no delays.
Production-ready code
We ship with CI/CD, error monitoring (Sentry), performance budgets, and accessibility audits. Your frontend is ready for real users from week 1.
Full documentation & handover
You get architecture decision records, a typed Storybook, and a runbook for your frontend. Your team can take over maintenance in under a day.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
