Overview

15 years in software engineering, the last 4 at Relay Foods, where I lead the real-time team. Mentored 8 engineers through their first promotion. Shipped a rewrite that took build times from 19 minutes to under 4. Before that: Deloitte and Natura &Co. Most at home with Go and WebSockets. I play football every Sunday.
