Overview

9 years in software engineering, the last 4 at Opal Robotics, where I work on the search team. Brought on-call pages for search down from 14 a week to 3. Reduced cloud spend on search by 20% in two quarters. Before that: Accenture and Cemex. Most at home with A/B testing and Java. I teach a weekend class on A/B testing.
