    At my heart, I am a sausage maker, which means that I do the really fun stuff like driving process and execution. Jealous, right? Nothing geeks me out more than starting with a few ideas on a whiteboard and eventually shipping a polished product. I've been in mobile since way before it was even a thing; in fact, I built one of the world's first mobile commerce applications. Though I grew up in NJ (Rutgers Strong!) I currently live on a small farm outside of Seattle, WA with my family and am a diehard supporter of local club and 2019 MLS Champions Seattle Sounders FC.
