Introduction
I prefer diversity in my work. I am a quick study, and like to try and learn new things. As I try not to stick to a very specific field, I’ve learned that combining ideas from different fields can result in more creative and innovative solutions.
Finding weird problems and good solutions are some of my strengths. On the other hand, working in strict and bureaucratic environments would probably not be.
Education
- 1997-2002, Computer Science. This involved classes from electronics to software design, including network engineering and system administration.
- 2003, Industrial Product Design. Which is the more practical and less abstract side of Industrial Design.
- 2005, LPI-1 Certificate. This is meant to show that you have a basic understanding system administration on Linux-based systems.
