CodenTree

CodenTree is a developer blog for practical Adobe Experience Manager (AEM) tutorials, interview preparation, Java, and modern web development. The goal is simple: clear explanations you can use in real projects.

AEM, OSGi, and HTL

Guides on AEM Sites, Sling, OSGi, HTL, Dispatcher, Cloud Service, and the pieces that show up in day-to-day AEM work.

Interview prep

Structured notes and Q&A for AEM, Java, and JavaScript interviews, written the way you would explain them to another developer.

Web engineering

Notes on React, Docker, Linux, Git, and related tools so the AEM work sits in a wider engineering context.

Written by Rizwan Zafar

Tutorials, interview notes, and implementation write-ups from hands-on AEM and web development work. If a guide is missing a step, use the contact page and it can be improved.
