About

Image of Karl Fleener

Iowa-raised, New York-based. I'm a front-end engineer who fuses engineering with design to transform solutions into beautiful and intuitive experiences.

Excited by structure and efficiency, I continually strive to deliver clean and elegant code, whether JavaScript, HTML or CSS.

When I'm not coding or pushing pixels, you can find me in the gym or on the volleyball court.
