VIA · Software Developer II — Identity platform
Nov 2024 — PresentSelf-hosted identity platform for passwordless auth
VIA's self-hosted Keycloak identity platform — the auth layer other VIA applications build on. It replaces passwords with W3C Verifiable Credentials held in a mobile wallet: scan a QR, present a credential, get logged in over standard OIDC. I develop the platform — the Keycloak plugin, the credential libraries, and the backend services behind it.
