Skills

Since 2016, I develop cross platform mobile apps. Over the time, I submitted over 6 apps to both Android and iOS app stores. My main specialization is React Native. I have developed multiple platform native modules for both company and open source context.

Lastly I was the leading developer for the mytonies® React Native app.

In 2016-2017, I have developed and open sourced 3 mobile games with the Java / Kotlin framework libGDX (Android and iOS).

I have developed and published multiple apps with React Native and Flutter. Professionally, I was also working on every aspect of the (React Native) app life cycle, from requirements, product owning up to End-To-End testing and store management. Privately, I have documented and open sourced many apps and also contributed to community projects. 

My further projects and open source work and interest include React, Flutter and Node.JS or Rust.

Technologies:
TypeScript, JavaScript, React, React Native, Node JS, Rust, GraphQL, ObjC / Swift, Docker, Flutter. Github Actions
