Alexander Schwartz is a Principal Software Engineer at IBM and a full-time maintainer for Keycloak. He builds secure authentication systems and guides developers through the complexities of single sign-on.
At conferences, he breaks down how to implement standards like OAuth 2.0 and OpenID Connect. His talks cover practical ways to shift identity management chores away from application code and how to use service level indicators for better observability.
When he isn’t presenting or working on Java and Kubernetes backends, he contributes to open-source projects in his spare time.
