I'm Zannatun Sheum, but most people call me Zann. A founder and senior software engineer in New York, with 11+ years building and testing production systems.

Off the clock, I trade the editor for a trail, a new country, or the kickboxing gym. Faith, curiosity, and a little discipline keep me moving.
