Prosthetic Arms
I started printing prosthetic arms and giving them away. No charge and no medical camouflage—if a kid wanted an upgrade, we designed an upgrade.

Reprogramming Reality
A book of paradoxes.
Made solo.
With: no one — wrote, designed & illustrated solo
Every chapter is built on a paradox—two ideas that can't both be true, held until they turn into something you can use.
Same trick as this site: two channels disagreeing until they make depth.

I've been building with 3D printers since 2012—back when you had to build the printer first. That work grew from objects into systems: prosthetic arms, Gotham City, a Times Square installation, manufacturing software, client portals, and the operating infrastructure behind them.
I work where design has to become operational—an object surviving a public plaza, or software surviving real users. Understand the constraint, build the thing end to end, leave evidence that it works.
Let's build
something.
Physical builds, digital infrastructure, and the hybrid problems that need both.
