Overview

16 years in software engineering, the last 2 at Harbor Care, where I lead the growth team. Moved 75% of growth traffic off a legacy monolith without a customer-facing incident. Wrote the experimentation service that now handles 66 million requests a day. Before that: eBay and PayPal. Former debater; now I argue with spreadsheets.
