TypeScript App Development DevelopersApp Development
Hire dedicated TypeScript developers who ship production-ready apps. 8-12 week MVPs with full code ownership and fixed pricing.
IRPR builds production-ready apps using TypeScript across the full stack. We use Next.js for web apps, React Native for mobile, and Node.js with Express for APIs. Every project uses strict TypeScript configuration and ESLint rules so code is consistent and maintainable.
We ship a working MVP in 8-12 weeks. Typical projects range from $80,000 to $250,000 depending on complexity and compliance needs. We have delivered apps for HIPAA, PCI-DSS, and SOC 2 environments. You own all source code from day one.
Startup CTOs hire us to build their first SaaS product without blowing their runway. Enterprise IT directors use us to modernize legacy apps into TypeScript. Product managers at mid-market companies trust us to ship their roadmap on a fixed schedule.

Why TypeScript for App Development
TypeScript catches errors at compile time, not in production. Our clients see 30% fewer bugs in their first month of use.
TypeScript adds static typing to JavaScript. That means refactoring is safer, APIs are self-documenting, and your team spends less time debugging runtime errors. We use TypeScript on every project because it pays back the investment within the first sprint.
Our developers contribute to the TypeScript ecosystem — we have published 12 open-source packages and fixed 5 issues on DefinitelyTyped. When you hire us, you get a team that knows the language inside out.
The Difference with IRPR's TypeScript Team
Most dev shops treat TypeScript like JavaScript with more code. We treat it as a first-class design tool.
Generic agencies write 'TypeScript' but skip strict mode, ignore discriminated unions, and produce any-typed messes. Our code passes strict:true with no errors and uses generics so your API types are always in sync.
We enforce these standards with automated linting in CI. Every PR must pass 50+ ESLint rules. The result is a codebase that new developers can read without context questions.
- Uses 'any' type in 20% of functions
- No strict mode — buggy config
- No type generation from DB or API
- Inconsistent linting across files
- No CI type check — breaks at build
- Hard to onboard new developers
- Zero 'any' types in 200+ projects
- strict:true enabled from day one
- Auto-generates types with Prisma and GraphQL codegen
- 50+ ESLint rules enforced in CI
- TypeScript build fails on type errors
- New devs understand code in < 2 hours
Our 4-Phase TypeScript App Process
From idea to production in 8-12 weeks. Every phase has a fixed deliverable and a clear price.
We break every project into four phases: Idea validation, Roadmap (design + architecture), Build (sprints), and Release. Each phase ends with a sign-off so you know exactly what you pay for before we start the next.
TypeScript runs through every phase. In the Roadmap phase we define the type models and API contracts. During Build we write tests against those types. At Release we ship compiled JavaScript with source maps for debugging.
What Ships in Every TypeScript Project
Every engagement includes a production-ready foundation, not just application code.
We don't deliver a zip file. You get a running application on your cloud account (AWS, GCP, or Azure) with monitoring, CI/CD, and documentation. Everything below is included in our fixed price — no add-ons.
The checklist covers infrastructure, code quality, and security. We've used this same setup for 200+ projects, so it's battle-tested.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel/Netlify
- Infrastructure-as-code (Terraform or Pulumi) on your cloud
- Strict TypeScript config with shared tsconfig-base
- ESLint + Prettier setup with 50+ custom rules
- TypeScript test suite (Jest + Testing Library, 80%+ coverage)
- Sentry error tracking with source maps
- Datadog or Grafana monitoring dashboards
- Swagger/OpenAPI docs or GraphQL Voyager
- Database migrations with Prisma and seed scripts
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Our average project is $150,000.
Senior engineers only
We don't hire juniors. Every developer on your project has 5+ years of TypeScript experience and has shipped at least 10 production apps. Our team averages 8 years of experience.
Full code ownership
You own all source code, designs, and documentation from day one. No licenses, no lock-in, no recurring fees. We push to your GitHub repository on the first day.
8-12 week MVP guarantee
We deliver a working, production-ready MVP in 8 to 12 weeks. 98% of our projects finish on time. If we miss the deadline, you get a 10% discount on the next phase.
Compliance built in
We have delivered TypeScript apps under HIPAA, PCI-DSS, SOC 2, and FERPA. Our infrastructure templates include encryption at rest, audit logs, and access controls out of the box.
Async-first, no micromanagement
We work async with daily standups via Slack and weekly demos via Loom. You don't need to be in the same time zone — 50% of our clients are in different continents.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
