About Me


Hey I’m Zack 😄

I’m an engineer, YC founder and curious person living in Waimanalo, Hawaii. I’m working on Pennie with my friend Rob, and I’m @zk on github and @heyzk on twitter and linkedin.

I was the CTO of Zaarly, and before that I wrote a data analysis and visualization application used to improve outcomes for Deep Brain Stimulation, a neurosurgical intervention for Parkinson’s disease and other movement disorders.
