Digital-Asset Custody

Backend custody service safeguarding cryptographic keys and signing transactions against per-user policies inside a trusted execution environment (Intel SGX); built first in Java, then re-engineered in Rust. Two granted patents came out of the work. Developed agile in quarterly, client-facing delivery cycles and shaped with customers from Europe to China: hands-on test deployments adapted to the customer's environment, regular customer presentations, and talks at a security conference at the University of Oxford.
