01 Introduction

Justin Cypret

it's SIGH-prit
Alias: Wildthing

I lead technology at Zamp. I like the spot where engineering and design run into each other (i make things), and I care about the details more than is probably healthy.

Mostly I get dropped into messy problems, find the shortest line through, and amplify the people around me until they're a multiple of where they started. Catching me is extra credit.

I'm a compulsive curator. If there's a better way to work, a better tool, or a weirdly specific product that does one thing perfectly, I've probably already found it.
