Description

Senior Java/Kotlin Developer with over 13 years of professional experience, and 7 years of experience as Lead Developer/Software Architect, I have worked for various renowned German companies in the banking, automotive, and research industries.

I work in backend, frontend, and mobile development. In the backend, I focus on Java/Kotlin and enjoy building microservices with the Spring Framework. For the frontend, I prefer using Angular.

I am very enthusiastic about cloud computing in general and have worked with Azure Cloud, AWS Cloud, and Google Cloud. Google Cloud is my favorite, however.

I am very flexible regarding database selection, from classic SQL to NoSQL databases. The important thing is that the selection fits the use case.
