I am a CAD Engineer for a Silicon Valley semiconductor company. My interests are reading, book collecting, building analog synthesizers, going to art galleries and museums, hiking, and cooking. This website is where I can experiment with things like javascript, animation, css (not yet), and rss (not yet).
