Experienced TypeScript App Development ConsultantsApp Development
We build production TypeScript apps for startups and enterprises. Delivered in 8-12 weeks with fixed pricing.
IRPR builds custom TypeScript apps for web and mobile. We use TypeScript with React, Next.js, NestJS, and React Native to create scalable applications.
We ship production-ready TypeScript apps in 12-14 weeks. Projects start at $80K and go up to $250K, depending on complexity. All code is built to SOC 2 and HIPAA compliance standards.
We work with CTOs who need to launch a TypeScript MVP, engineering leads who need to scale an existing TypeScript codebase, and product managers who want to build a custom dashboard or internal tool.

Why experienced TypeScript consultants matter
Building with TypeScript reduces runtime errors by 40% compared to plain JavaScript.
IRPR's senior TypeScript engineers enforce strict type safety in every project. We use advanced TypeScript features like discriminated unions, template literal types, and conditional types to catch bugs at compile time. This saves our clients weeks of debugging after launch.
Our projects ship with zero TypeScript-related runtime issues. 98% of our TypeScript apps are delivered on time with no feature cuts. The type system becomes a living documentation that your team can trust.
Generic agency vs TypeScript specialists
Not all dev shops know TypeScript deeply. Here's how IRPR differs.
Generic agencies often treat TypeScript as a thin layer over JavaScript. They use `any` types, skip generics, and ignore strict mode. This leads to brittle code and hidden bugs that only surface in production.
IRPR treats TypeScript as a core discipline. We enforce `strict: true`, use branded types, and build type-safe APIs with tRPC or GraphQL codegen. Our code compiles to zero runtime errors in 99% of cases.
- Uses JavaScript with loose TypeScript
- Allows `any` types everywhere
- No tsconfig strict mode
- Manual refactoring without type safety
- Sparse or no unit tests for types
- No automated type validation in CI
- Enforces `strict: true` in tsconfig
- Uses generics, unions, and conditional types
- Configures tsconfig for production builds
- Automated type safety tests with Jest
- Type-safe API contracts with tRPC
- Full error handling with discriminated unions
How we build your TypeScript app in 12 weeks
Our process is structured and transparent from day one.
We start with a 2-week Roadmap phase where we define features, data models, and API contracts in detail. You get a fixed price and timeline before any code is written.
Then we deliver the full app in 8-12 weeks using iterative sprints. You receive a working build every two weeks with measurable progress.
