By day, I work at Stack Overflow on a team that works behind the scenes to create and maintain services used by other teams in creating our products (Stack Overflow Q&A, Teams, Enterprise, etc..).
By night, I do more coding and writing, much of which you can read about on my blog: www.productiverage.com. I'm particularly interesting in the topics "performance" and "writing code that is unambiguous and expresses intent as clearly as possible". These are often seen as conflicting goals but that needn't be the case most of the time!
