Physics-trained. Block's heaviest internal GooseAI user. Frequent guest at industry data conferences. Rescue diver across 30+ countries between sprints.
A decade translating ambiguity into decisions — across YouNoodle, FiveStars, Medium, Square / Block, and now Intuit. Identity verification, sales analytics, e-commerce, and the infrastructure underneath. Polish-born, California-based, fluent in four languages, comfortable on a main stage and equally comfortable shipping the SQL.
