I'm Sam. I work on cryptography, computational complexity, and formal verification.
I like understanding what computers can and cannot do, building useful tools, and making mathematical arguments precise enough for a machine to check.
Here you'll find privacy protocols, complexity theory in Lean, terminal tools, and experiments that occasionally turn into games.
