#Hi, I'm Erik 👋

I maintain 3 open-source libraries with 8k stars combined and review about 400 pull requests a year. By day I build internal platforms: CI pipelines, deploy tooling, and the paved paths that keep 90 engineers shipping. 60 sponsors currently fund my triage habit, which my family describes as "reading strangers' stack traces for fun."
