Since more than ten years now I've been working as a java developer in different industries such as retail, logistics and automotive IoT. On this site I provide detailed informations about my work experiences, looking forward to employ them in your project as a freelancer.
As a fast learning, self confident and open minded person I'm used to get into new frameworks and environments in short time. Experienced mainly in backend development of Java EE and Spring-based server components I'm also looking for opportunities to step into the world of Angular 2 or Reactive.js.
Currently I'm not available for new projects. Living in Dresden/Germany with my family I prefer projects nearby. With the option of a part time home office after an introductory training I also accept more distant locations.
