Best TypeScript Development VendorDevelopment Vendor
We write strict TypeScript so your app ships without runtime surprises. 200+ products delivered in 8-12 weeks.
IRPR is the best TypeScript development vendor for teams that need production-grade apps fast. We use TypeScript across our full stack: React and Next.js on the frontend, Node.js and Express on the backend, and PostgreSQL or MongoDB for data.
Every project ships in 8-12 weeks. Fixed pricing starts at $80K and goes to $250K depending on scope. We build for HIPAA, PCI-DSS, and SOC 2 compliance out of the box.
Founders with a validated idea hire us to build their MVP. CTOs at mid-market companies ask us to rebuild legacy JavaScript apps in TypeScript. Product managers at funded startups choose us for scalable SaaS platforms.

Why IRPR is the Best TypeScript Development Vendor
We ship stable TypeScript apps faster because our senior engineers have used TypeScript since version 2.0.
TypeScript is our default language. Every new project starts with strict compiler flags: noImplicitAny, strictNullChecks, and exactOptionalPropertyTypes enabled. This catches null reference errors and type mismatches before the code runs. Our engineers have contributed to DefinitelyTyped and maintain several open-source TypeScript libraries.
We enforce code quality with ESLint, Prettier, and Husky pre-commit hooks. Every pull request is reviewed by two senior developers. Our CI pipeline runs type checks, unit tests, and integration tests with Jest and Playwright. The result is code that ships on time with 99.9% uptime.
How IRPR Differs from Other TypeScript Vendors
Other vendors sell TypeScript expertise but deliver messy JavaScript. IRPR writes TypeScript that compiles cleanly.
Many agencies claim to be TypeScript experts but their codebases have any types everywhere and ignored compiler errors. They treat TypeScript as a formatter, not a safety net. You end up debugging runtime errors that should have been caught at compile time.
IRPR treats TypeScript as a contract. We define interfaces for every API endpoint, database model, and external service. Our engineers write utility types and generics to make the code extensible without losing type safety. The code ships with full type coverage.
- Uses any types frequently
- Ignores TypeScript compiler errors
- No type safety on API responses
- Mixed JavaScript and TypeScript files
- No type checking in CI pipeline
- No shared type definitions between frontend and backend
- Strict type checks enabled (noImplicitAny, strictNullChecks)
- Zero compiler errors at merge time
- Full type validation on API request and response schemas
- 100% TypeScript across the entire codebase
- CI pipeline runs tsc --noEmit before every build
- Shared types package used by React frontend and Node.js backend
The IRPR TypeScript Development Process
We turn your idea into a working TypeScript product in 4 phases over 8-12 weeks.
Phase 1 is the Idea validation sprint. We review your requirements and create a technical specification with wireframes. This takes 1 week and costs $5,000. If you move forward, that amount is credited to the project.
Phase 2 is the Roadmap. We define the full scope, create a user story map, and estimate every feature. You get a fixed-price contract. No ambiguity, no hidden fees.
What Ships with Every TypeScript Project
You own everything we build. No lock-in, no hidden dependencies.
When the project is complete, you get full ownership of the source code. All repos are in your GitHub organization. We transfer all cloud accounts (AWS, Stripe, SendGrid) to your team. There is no ongoing license fee.
Every project includes a deployment guide, an architecture document, and a runbook for on-call engineers. Your team can maintain the code themselves or we can provide ongoing support at $150/hour.
- Source code in your GitHub organization with full commit history
- TypeScript project with strict compiler flags enabled
- CI/CD pipeline on GitHub Actions with type checking, linting, and tests
- Deployment to AWS ECS or Lambda with CloudFormation templates
- Database migrations and seed scripts for PostgreSQL or MongoDB
- Sentry error tracking and Datadog APM monitoring configured
- API documentation generated from TypeScript types using TypeDoc
- Unit and integration tests with Jest and Playwright with 80%+ coverage
- Architecture diagrams in Draw.io format
- 30 days of post-launch support with 4-hour response SLA

Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost upfront.
8-12 Week MVP Delivery
We ship a working product in 8-12 weeks. Your first sprint demo happens on day 14. You see real screens and working code before the halfway mark.
TypeScript from Day One
We do not migrate from JavaScript later. Every line of code is TypeScript from the first commit. No temporary type workarounds, no refactoring debt.
Compliance Built In
We build for HIPAA, PCI-DSS, and SOC 2 from the start. Encryption at rest, TLS 1.3, and audit logging are standard. No expensive retrofits.
