Bio
Iām a professional computer security researcher with an extensive background in Linux systems administration, computer networking, applied cryptography, and programming. Since childhood, Iāve enjoyed taking things apart and learning how they really work. Deep understanding allows me to push the boundaries of what is possible. Originally from California, I now live in London.
If youāre writing about me or my work, please use gender-neutral language to refer to me. I use they/them pronouns and prefer not to use a title, though āMxā is acceptable where one is required.
My family name is pronounced ākas-teh-LOO-cheeā.
