Herald is a cross-platform, end-to-end-encrypted messenger that brings the large-team support of Slack to secure messaging. Initially developed by Kalix Systems, it's now open source, and someday may even reach completion. The Herald UI was a solo design project for me, building on the many existing patterns for messaging tools and refining what I saw as rough edges—and bringing Signal-level security to platforms for large-team communication. The bulk of the development work was done by the Kalix Systems eng team, though I pitched in on client development.
