(he/him) Aging tech nerd, living in Silicon Valley. I'm an avid hiker and geocacher.

I've recently retired after 30+ years working in electronic design automation. After retiring last year and doing the training, my new part-time gig is as a park docent at Big Basin Redwoods. You might find me at the visitor center or on the trails.

Dungeon Webmaster, Open Sourcerer, and breakfast THAC0 enthusiast. Are you a friend of DeSoto? All paladins are bastards.

You may know me from making intros for LoadingReadyRun's streaming and YouTube content, or from being on the Desert Bus tech team, or for being a designer for Retro Games' line of mini retro computers, or for making random nerdy nonsense, or you may not know me at all – in which case, hi!
