Markus Heinemann

Over a two-month period, Heinemann enhanced developer experience and backend validation across two major repositories. For zitadel/zitadel, he improved the OIDC Playground by refining the user interface and updating documentation to clarify scope handling, reducing setup friction for new users through safer defaults and clearer guidance using React and JavaScript.
