Ramon Garciareymon
Physicist turned systems engineer working at the intersection of cryptography and adversarial infrastructure. I build protocol-level tools in Rust, break things to understand them, and write about what I learn along the way.
Currently — studying cryptography, building dag_exec (a Rust DAG executor) and ultrafold-micro (a BaseFold-like prover pipeline on top of it), plus a private Rust workspace for perp-arbitrage bot strategies. More on the about page.
