I recently made the jump from doing freelance web development work with most of my clients coming from craigslist to being the Director of User Experience at a software startup developing algorithmic trading software and doing UI/UX consulting for another company.
Right now I am working in C#/WPF for one company and Sencha (ExtJS) for the other.
Sorry if I came off that way. I am confident in my abilities to create awesome interfaces but I still have a lot to learn and a lot of time/practice to put in. My original comment was meant to be from the viewpoint of a "desingineer".
I know the article is probably referring to someone who is equally talented in development as they are design, able to create the backend along with the frontend, but I feel that being able to implement my designs in Windows Presentation Foundation, ExtJS, JQueryUI, Wordpress, etc make me a desingineer as well.
I possess: Taste, attention to detail and aesthetics, an understanding of human factors as they relate to computer interaction.
What does that make me? :)
