Case context

Overview

Mobile device administration needed a dedicated component for devices, applications, and users. I designed and implemented the Java/Wicket web interface that made centralized administration manageable for operations.

Built with Java 7 and Apache Wicket 6.8.0, the MDM system integrated JPA/Hibernate, Google Guice, and AJAX-powered interfaces. Checkstyle, PMD, and Findbugs kept quality and maintainability verifiable.

The tools are not the point by themselves. What matters is which system layers had to work together.
