From the warehouse floor to cybersecurity.

I'm a cybersecurity specialist with a growing background across risk, AI automation, and offensive security. I have proven experience through my Vendor Risk Management internship, — assessing the vendors Costco depends on and automating the manual tasks that slows security teams down —. I'm building my offensive security skills to eventually become a pen-tester. experience is also followed by years of high-pressure operational experience at Costco, where I learned how a large business operates.
