About

I'm a retired science teacher who writes educational apps for iOS. I've taught AP Physics, AP Biology, Honors Chemistry and a course in computer animation (Cinema4D). Programming is a self-taught hobby and I appreciate any help I get on SO.

I've also worked a luthier, special effects cinematographer and modelmaker, carpenter, iron worker and field engineer.
