Hey there! I'm Zach (aka zleinweber), a systems engineer who loves clean infrastructure, clean code, and good music.
By day, I lead the Infrastructure Systems Engineering team at a trading firm. We're the ones who keep the Linux systems — and the infrastructure services that rely on them — running fast, reliably, and transparently.
We manage critical infrastructure like Postgres, Redpanda, and Prometheus, with a strong emphasis on automation and reproducibility. If it can be expressed in Ansible or Terraform, it probably is.
I care deeply about making infrastructure intuitive — not just for machines, but for the humans who work with it.

Coming soon
I approach problems with calm rationality and methodical clarity.
In systems engineering, reliability is the core value — everything else is in sevice of that.
I also value kindness — in communication, in collaboration, and in the way we build tools for others to use.
