Why senior TypeScript consultants matter
TypeScript reduces runtime errors by 40% compared to plain JavaScript.
Senior TypeScript developers catch type errors at compile time. This means fewer bugs in production and faster debugging sessions.
Our team has shipped over 200 TypeScript projects. We follow strict linting rules, enforce type safety, and use strict mode everywhere.
Generic dev shop vs senior TypeScript consultants
Most agencies assign junior developers to your project. We don't.
Generic shops hire generalists who write JavaScript with occasional types. They skip strict mode and ignore edge cases.
IRPR assigns senior TypeScript engineers with 5+ years of experience. Every line of code is typed, tested, and reviewed.
- Uses 'any' type freely
- No strict mode
- No type definitions for third-party libs
- Mixed JavaScript/TypeScript codebase
- No automated type checking in CI
- Junior developers on your project
- Strict TypeScript mode
- Full type coverage
- Custom type definitions
- Pure TypeScript codebase
- TypeScript ESLint + Prettier in CI
- Senior engineers only (5+ years)
