Christoph Konrad Linke

Software Development Consultant, Software Engineer, and Web Developer in Düsseldorf, Germany

I'm a Software Development Consultant and Software Quality Engineer with a ISTQB Certification from Düsseldorf in Germany, living and working all around the world. I'm searching for and working in exciting projects to help implementing software with the best possible quality.

My preferred technologies are:




Further Skills:


C#, Java and Spring Boot

When I'm not developing software I like to make photos (like the one you can see as my header). That's one of the things I'm doing to chill out (beside reading good comic books :) or going to see my favourite soccer club). Another kind of relaxing for me is to engage with Penetration Testing and Malware Analysis because today also a developer has to have a deep understanding how software can be compromised to avoid such security issues.

If you want to hire me please feel free to send me an Email or to contact me via XING, Freelancermap ( or Gulp.
