I'm a developer. I write code, ship things, and keep them running.
Before that I spent a good while in reverse engineering and CTFs — the old writeups on this blog are from that era. I left them up because they still show up in search, and because the instinct never really goes away: when something is slow, mysterious, or undocumented, I'm the one who ends up reading the binary.
This is where I keep notes — mostly for myself, occasionally useful to someone else.
