// about

a brief description

I started out in Linux support and sysadmin work, then moved into software development, and eventually landed where the two meet. Today I build the platforms and pipelines other engineers depend on. That background means I’m as comfortable tracing a packet through a misbehaving cluster as I am writing the Go service that runs on it, or designing the Terraform module that spins up the whole thing.

Lately I’ve been working on the edge between platform engineering and AI, helping evaluate how language models reason about real infrastructure problems. Outside of work, I keep shipping reproducible, observable systems that I’d be proud to hand to any team.
