I have 18 years of experience in the aviation industry, doing all kinds of interesting stuff. I have worked in air vehicle design, mission engineering, system architecture, and been a professional war-gamer.
I do numerical analysis at home, build stuff with my kids, and am now looking into the possibility of ostrich grooming as a second career. I like to tinker with projects that I find useful, which by definition means that very few other people find them useful.
I also enjoy spending time imitating trees in hopes of fooling local wildlife...
