Hire Ken at Your Company

I'm a 33 year old developer and new dad living in Princeton, New Jersey. Outside of work, I've published several games, implemented simulations of bird flocks, slime molds, and pigmentation patterns in sea shells and animals. I'm currently exploring implicit neural representations for fonts based on DeepSDF, and building a puzzle game about dogs playing chess in my own game engine. I also enjoy speaking at JavaScript meet-ups and participating in live coding competitions in the Demo scene.
