About Me

Hey I’m Zack 😄

I’m an engineer, YC founder and curious person living in Waimanalo, Hawaii. I’m @zk on github and @heyzk on twitter and linkedin.

Previously I founded Pennie with my friend Rob, and before that I was the CTO of Zaarly. I’ve also helped improved outcomes for patients undergoing Deep Brain Stimulation, a neurosurgical intervention for Parkinson’s disease and other movement disorders.
