Freelancer profile translated to English.

Description

For many years, I have been professionally developing software for large companies such as Daimler Trucks AG or Deutsche Telekom AG, and therefore have extensive experience as a software developer and architect. My focus is on the design and development of applications based on Java/J2EE (backend, frontend with SSR technologies like JSF). I am accustomed to methodical work and have very good experience with defined software development processes such as Scrum.
