AEM Sites Developer Professional case studies
AEM Sites Developer Professional · Put your knowledge to work in context.
The Adobe Experience Manager Sites Developer Professional credential is designed for developers who build and maintain websites on Adobe Experience Manager Sites. It is aimed at practitioners who work hands-on with AEM's content repository, component and template model, server-side Java frameworks, and the delivery/caching layer in front of an author and publish topology. Typical candidates spend their days writing Sling models and OSGi services, configuring templates and policies, building editable components and dialogs, wiring client-side libraries and asset handling, and tuning Dispatcher rules for a production launch. Because the exam targets working developers rather than administrators or marketers, preparation should be project-based. The AEM Sites Developer Professional case studies are 5 cases and about 3,364 words.
