I’m a Frontend Developer by profession. But I worked in previous jobs also in Design, Editing, and 3D Animation. I even created Flash Animations and Multimedia CD-ROMs when this was still a thing.

I like the concept of the Renaissance Man and try out as many different professions as possible.

These are some of the projects I created over the last years.

The Traditional Colors of Japan

In 2007 I stumbled upon a Japanese book about the traditional colors of Japan by Nobyoshi Hamada. He listed all 250 colors with their color value in the appendix. I took some time to create an ASE file to be used with all common design software.

With this version of the website I finally dedicate an extra section to the colors, listing them all with their name and color values.

Journal & Blog

I have been writing articles on this website since 2007. The topics include programming, design, self-improvement, productivity, books, and films. The collection has been much bigger, but I deleted outdated and irrelevant articles. Since 2019 I also write a monthly article with recommendations of the past month.

Poetry / Writing


I started writing Haiku poetry some years ago inspired by the works of the Japanese Haiku poet Matsuo Bashō. I think Haiku is a fun, creative way to use limitation and brevity while saying something meaningful.

One of my passions is Sketchnotes or also called Visual Notetaking. In Sketchnoting you use visual language to quickly visualize ideas, notes, or thoughts. I create Sketchnotes since I first visited a workshop in 2015.
