- OIDC / OAuth 2.0 - understands token structure, identity federation, and broker login flows; must be able to configure an OIDC Identity Provider in Keycloak and interpret token claims
- Docker (multi-stage builds) - the Dockerfile is a full rewrite from a WildFly entrypoint model to a Quarkus two-stage build
- AWS
Good to Have

- Quarkus (datasource configuration, extension model)
- Keycloak administration - configuring realms, clients, identity providers, and mapper flows via the admin UI and REST API
