I am human.

I am a human who is currently marginally employed in Fairbanks, Alaska. I get paid by the University of Alaska sometimes for environmental sensor development work and I am also involved with a local Co-Working space and bike share startup. I do lots of Alaska things too, but spend a lot of time in windowless basements tinkering with electronics and digital fabrication tools.

I am a graduate from the Interactive Telecommunications Program at NYU, and building things is an important part of my identity.

I'm on Instructables and Github.
