I live in the space between 'it works on my machine' and 'it works for everyone, forever, without me' — AWS, IaC, and automation.

WORLD 1-1 · ABOUT

WHAT I ACTUALLY DO

I'm a cloud and infrastructure engineer working primarily across AWS — provisioning and maintaining ECS and EC2 environments, automating operational tasks with SSM, and keeping monitoring and logging pipelines healthy across multiple accounts.

Most of my work lives in the unglamorous space between "it works on my machine" and "it works for everyone, forever, without me." Automation, documentation, and just enough monitoring to sleep through the night — that's the job.
