Hi, I'm William Zujkowski

Senior Information Security Engineer who still gets excited about breaking and fixing things (legally, of course). Here, I share what works, what doesn't, and what keeps me up at 3 AM.

"A robot may not harm humanity, or, by inaction, allow humanity to come to harm."
— Isaac Asimov, The Zeroth Law

That nerdy kid devouring Foundation books under the covers with a flashlight? Yeah, that was me. Now I get paid to think about the same questions Asimov posed, except instead of psychohistory, I'm implementing actual security controls to keep AI from going full Skynet. Some dreams do come true – just with more YAML files than expected.
