Case context

Overview

An outdated iOS backend needed to become understandable and maintainable again. I worked through persistence analysis, code analysis, use case evaluation, and documentation analysis to make the backend capabilities clearer.

The system supported JSON and XML data exchange with iOS clients, CSV export via email, and SOAP integration. Java 7, Apache Wicket 6.3.0, Checkstyle, PMD, and Findbugs kept the technical base verifiable.
