Technical lead on Platform Infrastructure team, supporting a range of engineers and other teams. I spend time thinking deeply, to solve intractable problems around automation at any scale.I provide expertise in utilizing a wide range of technologies, predominantly, in no particular order: AWS / GCP / terraform / ansible / linux / jetty / nginx / haproxy / postgres / mongodb / bigquery / redis / nodejs / scylladb / apache superset / hadoop / spark / memcached / consul / kubernetes / GKE / helm / flux / argocd / atlantis / docker / podman.I build and maintain the tools (written in shell, ruby, and python) around automation and deployment that allow True Fit to expand to meet any need. I also architect, write, and maintain all approaches to infrastructure as code, and serve as a general purpose "whatever"Ops as needed.

I repair software (and now hardware) problems with computers of people in the five college consortium, and am part of the group that creates and updates the tools used by the consultant team. I created a from-scratch linux recovery environment for the team's use.

I learned, through apprenticeship with a shop, to build and repair guitars and other stringed instruments.
