What I work on

I’m an engineering leader from eu-north-1 working at Canonical, where I focus on making observability accessible and valuable for teams of any size.

My background is in open-source, developer communities, and building teams that ship.

I spend most of my time on the boring end of the problem: how to keep systems understandable as they grow, how to make on-call something a team can sustain, and how to make sure engineers can assess the reliability and availability of what they produce.

This site is where I keep essays I’ve written, talks I’ve given, and things I’m currently thinking about. If you read something here and want to push back on it — I’d rather hear that than a compliment.

Talk to me about

Engineering leadership, observability, Go, open-source, or hunting dogs. I have opinions on all of them!

Selected projects

Watchtower
Archived project that I ran for ~6 years with 24k+ stars on GitHub. Was the de-facto standard for running automatic updates of Docker containers when new images were available.
Shoutrrr
Notification library for gophers and their furry friends. Heavily inspired by caronc/apprise. Supports Slack, Telegram, Discord, and more.
Signal Studio
Diagnostic layer for OpenTelemetry Collector pipelines — static analysis, live metrics, and dry-run filter evaluation.
