TypeScript

TypeScript is my default language for production work. I use it to keep large codebases predictable across React Native apps, React web apps, and shared libraries.

This page is a short highlight and does not list all contributions or details.

What I delivered

Improved type safety and code quality across a React Native + React monorepo at Porsche Digital, including fixing TypeScript errors and tightening lint rules.
Stabilized the KulturPass codebase by resolving TypeScript issues and reinforcing the Redux architecture with strict typing.
Built and maintained a large TypeScript-based mobile app for Kicker and a long-running device configuration app for ABL.
Contributed to a shared design system with TypeScript components across React web and React Native in Barmer Puls.

Why it's a skill

I rely on TypeScript to model complex domains, enforce API contracts, and refactor safely at scale. It lets me move fast without breaking core flows, especially on long-lived products with multiple platforms.
