<About Me />

I’m Matt — Principal Solutions Engineer, security nerd, and habitual builder. I’m especially interested in deep technical security: C++, systems internals, detection, reverse engineering, and offensive tradecraft. I build things, break things, trace what happened, and write about what I learn. This site is where I keep the receipts. PS. Garbage-collected languages are for cowards. Accept the segfault like a real dev. PPS. Reading the card explains the card. Unless it's in Phyrexian.
