Projects

• DGA: Dependency Graph Analyser

  CLI tool for analysing and visualising Gradle dependencies in multi-module projects. This standalone tool uses the Gradle Tooling API to analyse a Gradle software project.

  The main driver behind this project was to get familiar with the Gradle tooling API and to experiment with graphs and how they can be visualised using Mermaid.

• Secure DNS Resolver

  Public secure DNS resolver configuration used by the Digital Society.

• Hacking Exposed

  Training material for an IT security course. I created the material and taught it in the period from 2018 to 2023.
