Intro
My name is Zach Margolis, it’s very nice to meet you! For work, I’m a software engineer. In the past, I’ve worked at Square (before it was called Block), and I’ve also done a tour of duty at the US Digital Service (before it was renamed), and worked on Login.gov via GSA’s TTS division. I graduated from UC Davis, go Aggies!

I pick up loose change when I find it on the ground and record it, and I have a small competition going with some of my family.
