Field notes on software, observability, and running teams.

Engineering leader at HiQ, where I help clients level up their engineering organizations through efficient ways of working, AI-empowered workflows, and cloud-native infrastructure. Over the years I've worked across software engineering, open source, developer tooling, and technical leadership, with a particular interest in helping teams build systems that are understandable, reliable, and worth operating. This site is where I publish essays, talks, and notes on software, observability, and running teams.
