production engineer, Open Source, and systems nerd

I am a Production Engineer at Meta, obsessed with reliability, performance, and squeezing every last bit of efficiency out of large-scale systems.

Over the years I've taken multiple systems from 0 → 1 → scale, working across incident response, capacity planning, infra hardening, and developer tooling.

I've also spent years contributing to open source, especially in and around CI/CD, systems libraries, and tooling – from improving developer experience in the Jenkins ecosystem to publishing libraries and GitHub Actions that make other engineers' lives easier.

When I'm not tearing apart yet another production issue, I'm usually lifting, boxing, or working on my "RaceConditioned" pillar a mix of disciplined living, fitness, and systems thinking applied to real life. I share what I learn across my socials and videos, talking about production engineering, infra, and long-term discipline.
