TypeScript Development CompanyDevelopment Company
We build production-grade applications with TypeScript. Ship faster with fewer runtime errors.
IRPR builds production-grade software using TypeScript across the full stack. We use Node.js, React, Next.js, NestJS, and PostgreSQL to deliver typed, scalable applications with minimal runtime errors.
Every TypeScript project ships in 8-12 weeks for an MVP. Pricing is fixed between $80K and $250K depending on scope. We support compliance standards like SOC 2, HIPAA, and PCI-DSS.
Startup CTOs hire us to build MVPs that investors can demo. Product managers at mid-market companies choose us to replace legacy JavaScript codebases. Enterprise engineering leads bring us in for TypeScript microservices and API gateways.
Types of software we ship.
Backend API Development
Build REST or GraphQL APIs with NestJS, Express, or Fastify. Includes Swagger docs, JWT auth, and PostgreSQL.
React Frontend Development
Create type-safe React apps with hooks, Redux Toolkit, and React Query. Ships with Storybook component library.
Next.js Full-Stack Applications
Build server-rendered apps with Next.js, API routes, and Vercel deployment. Includes SSR, ISR, and static generation.
NestJS Microservices
Develop modular microservices with NestJS, RabbitMQ, and Docker. Includes health checks, logging, and monitoring.

Why TypeScript matters for your product
TypeScript catches bugs at compile time, not runtime. That means fewer production incidents and faster iteration.
TypeScript adds static typing to JavaScript. This catches null reference errors, missing properties, and type mismatches before your code ever runs. For a 50,000-line application, that can prevent hundreds of bugs per release.
IRPR uses TypeScript on every project. Our teams enforce strict mode and no-explicit-any rules. The result: 40% fewer runtime errors compared to JavaScript-only projects, based on our internal metrics across 200+ products.
How we differ from generic TypeScript shops
Not all TypeScript development companies enforce the same standards. Here is what sets IRPR apart.
Many agencies write TypeScript that looks like JavaScript with occasional types. They skip strict mode, leave any types everywhere, and ignore linting rules. That defeats the purpose of TypeScript.
IRPR enforces strict TypeScript from day one. Every file must pass type checking, linting, and formatting before it reaches your repo. We also include unit tests, integration tests, and CI/CD pipelines in every project.
- No type safety enforcement
- Mixed JavaScript and TypeScript files
- No automated testing strategy
- No CI/CD pipeline setup
- Unclear code ownership after delivery
- Hourly billing with no fixed scope
- Full TypeScript strict mode enabled
- 100% typed code with no implicit any
- Unit + integration tests in every sprint
- CI/CD with GitHub Actions and Sentry
- Full source code ownership transferred
- Fixed price after the Roadmap phase
Our process for building with TypeScript
We follow a four-phase process that turns your idea into a production-ready TypeScript application.
Every project starts with a Discovery phase where we map out your requirements, user flows, and data models. We produce a technical architecture document with TypeScript types defined for all core entities.
The Roadmap phase gives you a fixed price and timeline. You get a detailed sprint plan with milestones, test coverage targets, and deployment schedule. No surprises.
What ships with your TypeScript project
Every project includes a complete, production-ready codebase and supporting infrastructure.
You get more than just code. We deliver documentation, deployment scripts, and monitoring tools so your team can take over immediately.
- Complete TypeScript source code with strict mode
- ESLint + Prettier configuration for code quality
- Jest test suite with 80%+ coverage
- CI/CD pipeline using GitHub Actions
- Docker containers for local and production environments
- API documentation auto-generated from Swagger/OpenAPI
- Sentry error tracking and performance monitoring
- Deployment scripts for AWS, Vercel, or your cloud
- README with setup instructions and architecture overview
- 1 month of post-launch support and bug fixes

Why teams hire us.
Fixed price, not hourly
Every TypeScript project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team averages 10+ years of experience. Every engineer is vetted for TypeScript expertise, system design, and communication skills.
TypeScript from day one
We never mix JavaScript and TypeScript. Every project starts with strict mode, full type coverage, and no implicit any types.
Full ownership of code
You own every line of code we write. We transfer the complete repository, including all git history, CI/CD configs, and documentation.
Compliance ready (SOC 2, HIPAA, PCI)
We build TypeScript applications that pass compliance audits. Our infrastructure supports encryption at rest and in transit, audit logs, and access controls.
Fast kickoff in 1-2 weeks
Most projects start within 2 weeks of signing. We use a streamlined onboarding process with pre-built TypeScript templates and CI/CD pipelines.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
