Andrew Koch

Staff software engineer

I've been building production software since 1999 — data platforms moving 100M+ records a week, payment-critical integrations, and the on-call, observability, and incident practices that keep them honest. These days my focus is AI-fluent engineering: using the new tools well, with the judgment of someone who has carried a pager.

This site has been my sandbox since 2005, when it ran Rails 1.0. The About page can answer questions about me — ask it anything.
