Case context

Overview

The data-processing backend needed a configuration layer that made central parameters, workflows, and administration controllable. I built that interface with Apache Wicket 1.4 and the surrounding Java stack.

Built with Apache Wicket 1.4 for component-based web development, the interface integrated JPA/Hibernate, Google Guice, MySQL, Tomcat deployment, and TestNG.

Technical context

Technology stack

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