Senior TypeScript Frontend Development VendorDevelopment Vendor
We pair senior TypeScript engineers with your team. Ship production UIs in 8-12 weeks.
IRPR is a senior TypeScript frontend development vendor. We build web applications with React, Next.js, Vue, and Svelte using strict TypeScript, Zustand for state management, Tailwind CSS for styling, and Playwright for end-to-end testing.
Every engagement ships a production-ready frontend in 8-12 weeks. Fixed pricing starts at $80K for a full-featured MVP and ranges up to $250K for complex, compliance-heavy projects (HIPAA, PCI-DSS, SOC 2).
We work with CTOs who need to scale frontend capacity without hiring, product managers launching new customer-facing apps, startups building investor-ready demos, and enterprise teams migrating legacy JavaScript to TypeScript.

Why a senior TypeScript frontend development vendor matters
TypeScript catches bugs at compile time. Senior engineers prevent architectural debt.
A senior TypeScript frontend development vendor writes strict types, enforces immutability, and designs state management that scales. Our teams use advanced generics, discriminated unions, and mapped types to make illegal states unrepresentable. Clients see 40% fewer production bugs compared to JavaScript-only teams.
IRPR assigns engineers with 8+ years of frontend experience. We have shipped TypeScript frontends for fintech apps handling $500M in transactions and healthcare platforms processing 10k patient records daily. Every pull request is reviewed by another senior engineer.
IRPR vs other frontend development vendors
Most agencies staff junior and mid-level developers on your project. We do not.
A typical frontend vendor assigns one senior architect and several juniors. This leads to inconsistent code, slow reviews, and a higher bug rate. IRPR sends a team of senior TypeScript engineers only. Every engineer has shipped at least 5 production apps.
We use fixed-price contracts, not hourly billing. You know the cost after a 2-week Roadmap phase. Our teams use TypeScript from day one, enforce 90%+ test coverage, and set up Sentry monitoring before the first sprint ends.
- Junior and mid-level developers on your project
- Hourly billing with frequent overruns
- JavaScript or loose TypeScript config
- Manual QA only, no CI/CD by default
- Slow code review cycle (2-3 days)
- No production monitoring setup
- Only senior TypeScript engineers (8+ years)
- Fixed-price contract, no surprises
- Strict TypeScript with advanced types
- CI/CD pipeline + Playwright tests from sprint 1
- Daily code reviews, 2-hour turnaround
- Sentry + New Relic monitoring pre-launch
How we deliver senior TypeScript frontend projects
Four phases from idea to production. Every phase includes a deliverable you can test.
IRPR uses a structured 4-phase process designed for senior teams. Each phase ends with a review meeting and a working artifact. You see code, not slides.
We start with a discovery phase to map user flows and choose the right tech stack. Then architecture, build, and deploy. Every two weeks you get a deployable increment.
What you get from a senior TypeScript frontend engagement
Every project ships a complete, production-grade frontend with full ownership.
You receive all source code, infrastructure code, and documentation. IRPR gives you everything you need to maintain and extend the frontend yourself or with your team.
- TypeScript source code in your private GitHub repo
- Component library published to Storybook (Chromatic)
- Unit and integration tests with 90%+ line coverage (Vitest)
- CI/CD pipeline using GitHub Actions
- Sentry error tracking with performance monitoring
- Tailwind CSS theme token file for consistent design
- Deployment scripts for Vercel / AWS / Netlify
- Technical README and API documentation

Why teams hire us.
Senior-only team on every project
Every IRPR engineer has 8+ years of frontend experience. No juniors or mid-levels. Your project gets a dedicated team with deep TypeScript, React, and architecture expertise.
Fixed price from the start
After a 2-week Roadmap phase, we give you a fixed quote. No hourly billing, no budget creep. The price you see is the price you pay for the agreed scope.
TypeScript experts, not generalists
We use strict TypeScript configuration, advanced generics, and discriminated unions. Our teams have written type definitions for custom SDKs and complex state machines. Fewer runtime errors, faster refactoring.
Fast kickoff in 1-2 weeks
We can start within 2 weeks of signing. We work async-first with daily overlap hours for US and European time zones. No months of onboarding.
Production-ready code every sprint
Every 2-week sprint ends with a working build on staging. We deploy early, test with Playwright, and monitor with Sentry. You see real progress, not slide decks.
100% code ownership and transparency
You own all source code, designs, and documentation. We grant you admin access to every tool (GitHub, Vercel, Sentry) from day one. No black boxes.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
