Overview

23 years in software engineering, the last 1 at Prism Pay, where I lead the product security team. Brought on-call pages for product security down from 22 a week to 1. Moved 92% of product security traffic off a legacy monolith without a customer-facing incident. Most at home with AppSec and React. I read too many books about cities.
