I am passionate about software development. I always love to create and learn new things. I have been working professionally on Android and web, and blockchain related projects, but I have also spend some experience with C# and the .NET Framework.

I am currently located in Berlin, Germany.

I am interested in software design and I always try to improve my skills, in order to build robust applications and services.

I love Open Source software and linux, my favorite distribution is Arch Linux which I use as my primary operating system.

20 Aug 2016 . news . Site Update Comments

The previous site was intended as a temporary solution, while I was working on the new one. Unfortunately due to work and life obligations the temporary solution of 2013 was rather long lived.

So after a really long period of time it is finally time for an update.

The new site is created using Jekyll and the Jekyll Personal Theme.

There is also an update planed for the MusicBee Remote website but this will happen after the update of the application and the creation of the new help guide.

Regards Kelsos.
