Building Traceway · Observability that tells you what to fix first
I'm a software engineer who lives in the PHP and Go worlds: Symfony, Laravel, and the tooling around them. These days most of my energy goes into observability, making it easy to know what's happening in production and how to fix it.
I write about OpenTelemetry, PHP internals, system design, and whatever I'm currently taking apart.
