Hi, I'm Kevin

I’m a Libre Software Craftsman.



My name is Kevin Ottens and I live in France. In general, I love to learn new things regularly which can be technical or about soft skills. Because of that depending who you talk to, you can get a very different picture:

  • Software Craftsman, since I’m a developer by trade and I like to share new insights on the job with others;
  • Free Software Hacker, since I’m involved in several projects, most notably with KDE;
  • Community Whisperer, since I study communities and help with their stewardship when I can;
  • Graphic Facilitator, since I like to do sketchnotes or help meetings using live scribing or innovation games;
  • Researcher, since I also have an academic background in general and a PhD in Artificial Intelligence in particular;
  • Aikidoka, since I’ve been practicing this martial art for years.

But really even in the different facets above, I always feel like there’s more to learn and more progress to be made. In fact I’m just a mere explorer.
