Fractional CTO, Long Run Advisory · Co-founder & CTO, Interstice Digital
Hands-on fractional CTO for teams that need to ship again. 20+ years scaling engineering organizations from 5 to 120+ engineers across blockchain, healthcare, and enterprise. 10 granted AI/ML patents. Currently building Canton Network settlement primitives and Interstice's institutional capital-markets platform.
🔐 conditional-holding-lock - Apache-2.0 reference implementation of a Canton Network Token Standard CIP. Interface package and TestTokenV2 adapter with executable proofs of byte-domain hashing, persistent receiver authorization, one-step locking, and atomic two-registry settlement.
✍️ erc-spend-grants - Draft ERC for portable spend grants. One EIP-712 signature lets a delegate spend native currency and ERC-20s under per-call, rolling-window, and lifetime caps. Includes a Solidity reference registry, TypeScript hashing and rendering, golden vectors, and an ERC-7730 display descriptor, with a registry deployed on Arc testnet.
🤖 Application Intelligence - Transforming traditional QA into AI-powered UX feedback. Moving beyond test generation toward understanding how users actually experience software.
