Selected work

Work I'm proud of.

A few projects from my day job: what they do and the scale they run at.

Northwind Labs · internal platform

A deploy pipeline teams actually use

Replaced three hand-rolled release scripts with one pipeline: build, test, canary, promote. Adoption went from a pilot team to every service in two quarters because the first deploy took ten minutes, not a day.

Designed the retry-safe write path for a payments API handling millions of requests a day, with request fingerprints, an outbox, and a replay tool for support.
