Patty is a nomadic UI/UX designer who codes a bit and gravitates toward creative strategy, branding, front-end coding, AB testing, and illustration. She's worked with companies such as Kissmetrics, Dice, Roc Nation, and more. Patty designs for user needs and is fond of JTBD for user research and atomic design for iterative prototyping. She believes that people don't want to buy a quarter-inch drill. They want a quarter-inch hole (TL).
