Why TypeScript Matters for Your App
TypeScript catches errors at compile time, not runtime.
Our TypeScript codebase uses strict null checks and noImplicitAny. Every pull request runs ESLint and Prettier before CI. We catch 80% of potential bugs before they reach production.
TypeScript integrates directly with your existing JavaScript. You get better IDE support, refactoring confidence, and self-documenting code. We have shipped 200+ TypeScript projects with zero production type-related incidents.
What Sets IRPR Apart from Other TypeScript Agencies
Most agencies sell you a team, then hand you untyped JavaScript. We commit to TypeScript from day one.
We enforce a type-first architecture with strict tsconfig. Every endpoint has a generated type, every component has a Props interface. No any, no magic strings.
Our developers average 8 years of TypeScript experience. We don't train juniors on your dime. You get a senior engineer who writes code that looks the same as your internal best practices.
- Uses any and loose types
- No automated type checking in CI
- Mixed JavaScript and TypeScript files
- No shared type contracts between frontend and backend
- Slow refactoring due to missing type coverage
- Documentation outdated from day one
- Strict TypeScript config with noUncheckedIndexedAccess
- TypeScript linting and type checking in every CI run
- 100% TypeScript across the stack
- Auto-generated types from Prisma and GraphQL schemas
- Instant refactoring with zero regressions
- TypeDoc auto-generated API docs
How We Build Your TypeScript App
Our process turns your idea into a production-ready TypeScript app in 8-12 weeks.
We start with a 2-week discovery phase to map user flows, data models, and API contracts. Then we deliver working software in 2-week sprints with transparent demos.
Final release includes a fully typed codebase, CI/CD pipeline, and automated tests. You own everything from day one.
What Ships with Every TypeScript App
Every project includes these deliverables by default.
You get a production-ready TypeScript codebase with full type coverage. No placeholders, no deferred technical debt.
All projects include a CI/CD pipeline on GitHub Actions, Sentry error tracking, and a staging environment on Vercel or AWS.
- Source code in your Git repo with full commit history
- Strict TypeScript configuration (tsconfig.json)
- CI/CD pipeline on GitHub Actions with type checking
- Sentry error tracking with source maps
- Unit tests with Jest and React Testing Library
- API contract documentation via TypeScript types
- Prisma schema with auto-generated types
- Storybook for UI component library
- Deployment scripts for Vercel or AWS
- One year of support and maintenance after launch
What we ship in this practice.
Real-Time Fintech Dashboard
Built a TypeScript dashboard for a fintech startup handling 500K transactions daily. Uses Next.js, PostgreSQL, and WebSockets. Reduced page load time by 60% and improved type safety caught 40% more data validation errors pre-deploy.
E-Commerce Storefront Migration
Migrated a legacy JavaScript storefront to Next.js with TypeScript. Improved Lighthouse scores from 45 to 92. Stripe integration handled 10K+ orders per month with zero payment errors.
Healthcare Patient Portal
Developed a HIPAA-compliant portal using Next.js and Prisma. TypeScript ensured all PHI fields were typed and encrypted. Reduced manual data entry by 8 hours per week per clinic.
Real Estate MLS Search Platform
Created a property search platform with TypeScript, GraphQL, and PostgreSQL. Handles 1M+ listings with sub-second search. TypeScript type sharing between frontend and backend eliminated data mapping bugs.
SaaS Analytics Tool
Built a multi-tenant analytics dashboard for a B2B SaaS. Uses TypeScript, React, and D3 for charts. Onboarded 200+ enterprise clients with 99.9% uptime. TypeScript strict mode prevented cross-tenant data leaks.
Logistics Tracking System
Developed a real-time tracking platform with TypeScript, Node.js, and PostgreSQL. Handles 50K+ shipments daily with WebSocket updates. TypeScript union types modeled all shipment states, reducing bug reports by 70%.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after a 2-week discovery phase. No hourly billing. No surprise invoices. You know the cost before we write a line of code.
Senior TypeScript Engineers Only
Our team averages 8 years of TypeScript experience. We never outsource or staff juniors. Each engineer writes production-ready type-safe code from day one.
TypeScript-First Architecture
We use strict TypeScript config with noImplicitAny and strictNullChecks. Every component, API endpoint, and database query is typed. You get a codebase that compiles without errors.
Compliance Ready by Default
We build to SOC 2, HIPAA, and PCI-DSS standards. TypeScript helps enforce data validation and access control at compile time. Our audit trail is generated from type definitions.
Async-First, Time-Zone Friendly
We work async across 50+ countries. Our communication is clear, written, and recorded. You get daily updates and a live Notion board. No time-zone calls needed.
200+ Products Shipped
We have delivered 200+ TypeScript projects across 50 countries. 98% of projects shipped on time. Each project includes a typed codebase we will support for a year.
