About

I finished Running Start at Bellevue College with an Associate's degree and I'm now studying Cybersecurity at Seattle University. Outside of code, I spent four years on varsity wrestling as team captain, three in jazz band, and time working retail — none of which show up in a stack trace, but all of which taught me the same lesson: show up, do the unglamorous work, and don't skip steps.

On the security side, I'm working toward the ISC² CC credential and building out a personal pentesting lab — numbered, versioned vulnerable apps I build, break, and document like real engagements. That habit carries over into how I build: I'd rather find my own bugs than let a production user find them first.
