Premium TypeScript Development AgencyDevelopment Agency
We build production-grade apps with TypeScript. Expect clean code, strict types, and full test coverage from day one.
IRPR is a premium TypeScript development agency. We use TypeScript across the full stack — Node.js, NestJS, Next.js, React, and React Native — to build type-safe, maintainable applications. Every project ships with strict null checks, eslint configuration, and a CI/CD pipeline that validates types on every commit.
Typical delivery timelines are 8-12 weeks for an MVP, with fixed pricing between $80K and $250K depending on scope. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Our senior engineers work directly with your team, not offshore juniors.
We are hired by startup CTOs who need a production-ready MVP in 12 weeks, funded founders building scalable SaaS platforms, enterprise teams migrating legacy JavaScript to TypeScript, and product managers who want a fixed-price, on-time delivery partner.
Types of software we ship.
TypeScript backend API
Build a type-safe REST or GraphQL API with NestJS, Prisma, and PostgreSQL. All endpoints validated at compile time.
TypeScript web app
Develop a full-stack web application with Next.js, React Query, and tRPC. TypeScript from database to UI.
TypeScript mobile app
Cross-platform mobile apps with React Native or Expo. Shared types between backend and mobile reduce bugs by 40%.
TypeScript monorepo
Structure large projects with Turborepo or Nx. Shared packages, enforced boundaries, and fast incremental builds.
TypeScript library / SDK
Design and publish developer tools or client SDKs with full type definitions, automated releases, and semantic versioning.
TypeScript SaaS platform
Multi-tenant SaaS with Zod validation, tRPC procedures, and a Prisma-driven data layer. Ships with Stripe integration and auth.
TypeScript data pipeline
ETL pipelines with TypeScript, BullMQ, and Redis. Typed contracts between stages prevent runtime surprises.
TypeScript chatbot / AI
Integrate LLMs with typed prompts and structured outputs. Use LangChain with TypeScript for reliable agent workflows.
We build for every business type.

Why a premium TypeScript development agency matters
TypeScript catches errors before they reach production. A premium agency enforces this discipline across every layer.
Standard JavaScript projects often ship with undefined is not a function errors in production. With TypeScript, IRPR eliminates entire categories of bugs at compile time. Our codebases routinely achieve 100% type coverage and zero implicit any.
We use strict TypeScript configuration, Zod for runtime validation, and tRPC for end-to-end type safety. This means your frontend knows exactly what the backend will return. No manual API documentation. No runtime surprises.
How we differ from generic JavaScript shops
Most agencies treat TypeScript as a decoration. We treat it as the foundation.
Generic shops write JavaScript first and add type annotations later. They use any liberally, skip strict mode, and avoid advanced types. This leads to brittle code that offers little real safety.
IRPR writes TypeScript from the first commit. Our projects use strict mode, discriminate unions, branded types, and conditional types where needed. We also enforce these standards in CI.
- uses any in type annotations
- no strict mode in tsconfig
- skips runtime validation
- no automated type tests
- does not enforce coverage thresholds
- mixed JavaScript and TypeScript files
- strict mode with noUnusedLocals and noUncheckedIndexedAccess
- 100% type coverage enforced by codegen
- Zod schemas for runtime type safety
- type tests with ts-expect-error patterns
- CI gate on type-check --noEmit
- monorepo with shared types across all services
Our TypeScript project delivery process
From idea to production in 12 weeks, with fixed scope and fixed price.
IRPR follows a four-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we define the full tech stack, architecture, and a fixed price contract. No surprises later.
During Product, we build in 2-week sprints with daily stand-ups, Jira tracking, and continuous deployment. Every sprint ends with a demo of working TypeScript code.
What ships with every TypeScript project from IRPR
We do not deliver working code. We deliver production-grade systems.
Every deliverable includes automated testing, documentation, and operational readiness. You get a system that runs without your team guessing how to maintain it.
Our engineers set up CI/CD, error tracking, and monitoring as part of the standard build. No extra charges for deployment.
- Full TypeScript source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (type-check, lint, test, deploy)
- Sentry error tracking with source maps
- Datadog or New Relic performance monitoring
- Zod validation schemas for every API endpoint
- Automated unit, integration, and e2e tests (Vitest / Playwright)
- API documentation generated from TypeScript types with TypeDoc
- Strict tsconfig with noUncheckedIndexedAccess and exactOptionalPropertyTypes
What we ship in this practice.
Real-time collaboration dashboard
We built a TypeScript-based collaboration dashboard for a remote team tool. The app uses WebSockets with Socket.IO, React, and TypeScript. It reduced sync latency from 2s to 150ms.
Fintech payment reconciliation engine
For a New York fintech startup, we built a TypeScript backend with Node.js and PostgreSQL. The system processes 10,000+ transactions per minute with zero runtime errors.
HIPAA-compliant patient portal
We developed a full-stack TypeScript application for a healthcare provider. Next.js frontend, NestJS backend, and TypeORM for MySQL. The portal reduced manual data entry by 8 hours per week per clinician.
Ecommerce marketplace platform
We built a multi-vendor marketplace with Next.js, Prisma, and Stripe. TypeScript ensured type safety across the entire order flow. The platform handles $2M in monthly transactions.
Real estate MLS integration service
A real estate brokerage needed a type-safe MLS API client. We built it in TypeScript with Zod schema parsing, connected to Reso Web API. Integration time dropped from 6 weeks to 2 weeks.
EdTech assessment engine
We created an adaptive testing platform using TypeScript on Node.js and React Native. The engine uses typed state machines to manage question progression. It supports 5,000 concurrent users.
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. We have delivered 200+ projects on this model.
Senior TypeScript engineers only
Our engineers average 8+ years of commercial experience and are TypeScript experts. We do not outsource or use junior developers. Every line of code is reviewed by a senior.
End-to-end type safety
We enforce strict TypeScript from database to UI. Prisma generates typed queries, tRPC ensures API contracts, and Zod validates runtime data. No more undefined errors in production.
Full code ownership
You get complete source code, CI/CD pipelines, and documentation. No black boxes, no ongoing license fees. Your team can take over or modify the code immediately.
Production-ready in 8-12 weeks
Our 4-phase process (Idea, Roadmap, Product, Release) delivers a production-grade MVP in 8 to 12 weeks. We handle hosting, monitoring, and deployment as standard.
Enterprise compliance built in
We have built TypeScript applications for HIPAA (healthcare), PCI-DSS (fintech), SOC 2 (SaaS), and FERPA (edtech). Compliance is not an afterthought — it is part of the initial architecture.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
