Why TypeScript Matters for Your App
TypeScript catches bugs at compile time, reduces runtime errors, and makes code easier to refactor.
IRPR has shipped over 200 products, all built with TypeScript. Our engineers enforce strict type checking, which prevents null pointer exceptions and undefined property errors. This results in 40% fewer bugs in production compared to equivalent JavaScript codebases.
TypeScript also speeds up onboarding. New developers can understand the codebase by reading type definitions. We use JSDoc and typed interfaces so your team can take over after delivery with minimal friction.
Generic Dev Shops vs IRPR: The TypeScript Difference
Not all developers treat TypeScript as a first-class citizen. Here's how we differ.
Many agencies treat TypeScript as a thin layer of types on top of JavaScript. They skip strict mode, allow `any` types, and don't set up linting rules. This defeats the purpose of TypeScript and leads to the same runtime issues.
IRPR starts every project with `strict: true` in tsconfig, configures ESLint with TypeScript-specific rules, and runs type checks as part of CI. We also enforce no-unsafe-any and strict null checks to guarantee production reliability.
- Uses `any` type freely
- No strict mode in tsconfig
- Hourly billing without fixed scope
- No CI/CD pipeline included
- Code has no automated tests
- No documentation or type annotations
- Strict TypeScript with `strict: true`
- 100% type coverage on all modules
- Fixed price per project from $80K
- CI/CD with GitHub Actions and Husky
- Unit tests with Vitest and coverage >80%
- Automated API docs with Swagger from type definitions
Our Process for Building Your TypeScript App
We follow a four-phase approach that keeps projects predictable and transparent.
Every engagement starts with a focused Discovery phase. We learn your domain, users, and goals. In week 2, we deliver a Roadmap document that includes the full tech stack, database schema, API contracts, and a fixed price.
Development happens in 2-week sprints. You see progress every cycle. By week 8-12, you have a production-ready app deployed on AWS or Vercel, with monitoring and error tracking already in place.
What Ships With Every TypeScript Project
Every deliverable includes the essential infrastructure for a production-grade app.
IRPR includes infrastructure as code, monitoring, and error tracking in every project. You get a complete stack that is ready for scaling and maintenance by your team.
We also include a 30-day post-launch support window. During this period we handle hotfixes and answer questions about the codebase.
- Source code in your private GitHub/GitLab repo
- TypeScript strict configuration with lint rules
- CI/CD pipeline with GitHub Actions (test, lint, build, deploy)
- Sentry error tracking and performance monitoring
- Database schema (Prisma) with migrations
- Unit tests with Vitest (minimum 80% coverage)
- API documentation (Swagger/OpenAPI) auto-generated
- Deployment scripts for AWS or Vercel
- Full code ownership (no licenses, no lock-in)
- 30-day post-launch support and documentation handover
What we ship in this practice.
Real-Time Data Dashboard for Fintech
IRPR built a real-time financial dashboard using Next.js, TypeScript, and WebSockets. It reduced page load time by 60% and let users see live portfolio updates. The client onboarded 200 new users in the first month.
Multi-Tenant SaaS Platform
We developed a multi-tenant CRM with Next.js, TypeScript, PostgreSQL, and Clerk for auth. The platform handles 10,000 active users with sub-200ms API response times.
Mobile Health App (React Native)
A React Native and TypeScript mobile app for patient medication tracking. It integrates with Apple Health and Google Fit. The app reduced missed doses by 40% in a 6-month pilot with 500 patients.
E-commerce Checkout Redesign
IRPR rebuilt the checkout flow for a large e-commerce brand using Next.js, TypeScript, and Stripe. Conversion rate increased by 22% after removing page reloads and adding client-side validation.
Collaborative Document Editor
We built a real-time collaborative document editor with operational transforms using Yjs, Node.js, and TypeScript. The editor supports 50 simultaneous users with latency under 100ms.
Developer API Portal
A public API portal with auto-generated TypeScript SDKs and interactive documentation. The portal reduced integration time for partners from 4 weeks to 2 days.
Why teams hire us.
Fixed Price, Not Hourly
IRPR gives you a fixed price after the Roadmap phase in week 2. No hourly billing, no scope creep charges. The price covers the entire project including testing and deployment.
Senior Engineers Only
Every IRPR developer has 8+ years of experience and deep TypeScript expertise. No juniors, no outsourced teams. You work directly with the engineers who build your app.
TypeScript Strict Mode by Default
We configure `strict: true` from day one and enforce it with CI checks. This eliminates entire classes of bugs and makes your codebase maintainable for years.
Full Code Ownership
You own everything we produce. Source code, documentation, CI configurations, and deployment scripts. No licenses, no royalties, no vendor lock-in.
CI/CD and Monitoring Included
Every project ships with automated testing, continuous deployment, and error tracking via Sentry. Your team can deploy changes on day one with confidence.
8 to 12 Week Delivery Guarantee
IRPR guarantees delivery within 8 to 12 weeks for most projects. We have a 98% on-time record across 200+ deliveries.
