Selected work

A sample of projects.

Identity verification infrastructure, protocol design, and data governance.

Digital identity

Standards-based identity verification platform

Helped design and build a platform that lets organisations issue, hold and verify credentials using open standards rather than proprietary formats. The work followed a standards-first approach grounded in W3C Verifiable Credentials and the ISO mobile driving licence specifications.

Extended a messaging protocol to support native communication rails across multiple distributed networks, enabling addresses on each network to message each other directly.

Protocol design
Secure messaging
Network interoperability

Protocol storage

Resilient protocol storage

Designed storage and retrieval for messages using peer-to-peer distribution, paired with an IMAP-compatible protocol so messages could be received through standard email clients.
