Professional TypeScript Development PartnerDevelopment Partner
We build production-grade TypeScript apps in 8-12 weeks. Fixed price, senior engineers, zero fluff.
IRPR builds production-grade TypeScript applications for startups and enterprises. We use React, Next.js, Node.js, NestJS, Prisma, and PostgreSQL to ship scalable web apps, APIs, and SaaS platforms.
Every project starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. MVPs ship in 8-12 weeks. Projects range from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA.
Founders hire us to validate an idea with a working MVP. CTOs hire us to build internal tools and customer-facing platforms. Product managers hire us to replace legacy code with modern TypeScript. Agencies hire us to handle overflow engineering work.

Why you need a professional TypeScript development partner
TypeScript reduces runtime errors by 40% compared to plain JavaScript. But you need a team that uses it right.
IRPR has shipped 200+ TypeScript applications across 50 countries. We use strict mode, generics, union types, and mapped types to catch bugs at compile time. Our codebases have zero implicit any and full type coverage.
Every project includes a typed API layer with Zod or io-ts validation. This means your frontend and backend share the same types. No more mismatched payloads or runtime crashes. We also set up ESLint with TypeScript rules and Prettier for consistent formatting.
Generic dev shop vs IRPR TypeScript partner
Not every agency treats TypeScript as a first-class language. Here is how IRPR differs.
Many shops use TypeScript like JavaScript with occasional types. They skip strict mode, ignore generics, and ship code with implicit any. This defeats the purpose of TypeScript.
IRPR treats TypeScript as a design tool. We define types before writing logic. Every function has a typed signature. Every API response is validated at runtime. Our code compiles clean on strict mode with no exceptions.
- Uses loose TypeScript config
- Leaves implicit any in code
- No runtime type validation
- Mixed JavaScript and TypeScript files
- No type sharing between frontend and backend
- Slow builds due to poor tsconfig
- Strict mode enabled from day one
- Zero implicit any policy
- Runtime validation with Zod or io-ts
- 100% TypeScript codebase
- Shared types via monorepo or NPM package
- Optimized tsconfig for fast incremental builds
Our TypeScript development process
We follow a 4-phase approach that starts with a fixed-price Roadmap and ends with a deployed product.
Every project begins with a 2-week Roadmap phase. We interview stakeholders, map user flows, design the data model, and produce a detailed spec with wireframes. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints with daily standups, weekly demos, and continuous deployment. You see working software every 14 days. We write unit tests, integration tests, and end-to-end tests in TypeScript using Vitest and Playwright.
What ships with every TypeScript project
Every engagement includes a complete delivery package. You own everything from day one.
We do not hand off a zip file. You get a production-grade codebase with CI/CD, monitoring, and documentation. Your team can take over immediately.
All code is written in strict TypeScript with full type coverage. We include a typed API client, database schema, and migration scripts. You also get a README with architecture decisions and runbooks.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Vercel or AWS
- Sentry error tracking with source maps
- Datadog or New Relic monitoring dashboards
- Full test suite with Vitest and Playwright
- TypeScript strict mode with zero errors
- Database schema and migration scripts (Prisma or Drizzle)
- API documentation with Swagger or GraphQL schema
- Deployment playbook and runbook
- 1-hour handoff session with your team
What we ship in this practice.
SaaS billing platform for a fintech startup
Built a multi-tenant billing system with Stripe integration, usage-based pricing, and automated invoicing. Tech stack: Next.js, TypeScript, Prisma, PostgreSQL, Stripe. Reduced billing errors by 90% and cut manual invoicing from 20 hours per week to zero.
Telehealth patient portal for a healthcare provider
Developed a HIPAA-compliant patient portal with video visits, messaging, and appointment scheduling. Tech stack: React, TypeScript, Node.js, WebRTC, AWS. Handled 10,000+ monthly visits with 99.9% uptime.
Real estate MLS integration for a proptech platform
Created a property search engine with real-time MLS data, map-based UI, and automated lead capture. Tech stack: Next.js, TypeScript, Mapbox, GraphQL, PostgreSQL. Increased lead conversion by 35%.
Ecommerce checkout optimization for a DTC brand
Rebuilt the checkout flow with one-click purchase, saved payment methods, and real-time inventory checks. Tech stack: React, TypeScript, Shopify Storefront API, Stripe. Reduced cart abandonment from 70% to 45%.
Learning management system for an edtech company
Built a custom LMS with course authoring, student progress tracking, and live quizzes. Tech stack: Next.js, TypeScript, PostgreSQL, AWS S3, WebSockets. Supported 5,000 concurrent students during peak hours.
Internal operations dashboard for a logistics firm
Developed a real-time dashboard for tracking shipments, warehouse inventory, and delivery routes. Tech stack: React, TypeScript, Node.js, PostgreSQL, Mapbox. Reduced manual data entry by 8 hours per week.
Why teams hire us.
Senior TypeScript engineers only
Every engineer on your project has 5+ years of TypeScript experience. We do not use junior developers or offshore teams. Our team averages 10 years of professional experience.
Fixed price, not hourly
You get a fixed price after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep. If we need more time, we cover the cost.
TypeScript strict mode from day one
We enable strict mode in tsconfig.json on the first commit. Every function has typed parameters and return types. No implicit any, no loose null checks.
Full test coverage with TypeScript types
We write unit tests, integration tests, and end-to-end tests in TypeScript. Tests use the same types as production code. This means your tests catch real bugs.
Shared types across frontend and backend
We use a monorepo or shared NPM package to keep types consistent. Changes to the database schema automatically update the API client types. No more manual type sync.
Production-grade CI/CD and monitoring
Every project ships with automated testing, type checking, and deployment. We set up Sentry for error tracking and Datadog for performance monitoring. You see production issues before users do.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
