I'm a software engineer with 10+ years in Staff+ roles, specializing in distributed systems, platform engineering, and infrastructure at scale. Currently a Principal Engineer at Midokura, building GPU infrastructure and automation for AI workloads. Previously at New Relic, Adevinta (serving 1500+ engineers), Last.fm, and others (see about for more).

Below are some pieces I wrote. You can get updates via mailing list using the form below, or via RSS feed (expect low frequency, long form content.) I'm also at Twitter/X and Bluesky.
