A wireless HID keystroke injector solution with a remote payload interface. This was coded in Go, but the project is not finalized yet. While the core functionality is complete there is still a long list of features in my backlog.

Data Security Intro

A website that shows you the basic key concepts of data security. This isn't aimed at senior security engineers but rather people that have some technical knowledge and look for an introduction the exciting world of data security.

You are guided in six parts through theoretical and practical information and examples. Additionally, you will be shown how to hone your skills with the help of Webgoat, Over The Wire (OTW), Metasploitable 2, etc.


A simple experiment for a cross-platform application made with .NET MAUI Blazor to manage your cooking recipes and search & import new ones from external sources. The app works on Android, iOS, macOS, Windows, and Tizen.
