experience
Mar 2025 — Now
Halcyon — Platform Engineer
Own the Kubernetes platform for forty product teams: cluster upgrades as Argo Workflows, GPU node pools with time-slicing, and the on-call rotation that keeps it honest. Cut p99 deploy time from 40 to 9 minutes.
Jan 2024 — Now
kube-shim — Maintainer · open source
A small scheduler extender that lets batch jobs borrow idle GPU capacity. Reviews, releases, and the occasional 3 a.m. bug from a timezone I have never visited.
Jun — Dec 2023
Northwind Analytics — Site Reliability Engineer, intern
Rebuilt the alerting stack on Prometheus and Alertmanager, wrote the runbooks nobody had, and got the pager down from 30 pages a week to 4.
