01 / A little about me

Hi, I’m Luke.

Luke Petrosky

I like finding ways to make everyday work a little easier. When a task feels unnecessarily complicated or repetitive, I start thinking about how to improve it. That’s what draws me to platform engineering and automation: solving problems that make someone’s day a little less frustrating.

I’m also curious about where AI can help, including here. I used it to help build this site, while shaping the content and structure myself to make sure it reflects my experience and how I think about my work.

02 / The path so far

Built on experience.
Always building.

A foundation in cybersecurity. A growing focus on platform engineering.
