I am a Munich-based Tech Lead, Chief Information Security Officer (CISO), and Security Consultant specializing in tailored IoT projects. My tech journey started in the era of Commodore 64s and 386DX machines, which eventually led me to a degree in Computer Science and years of working as a Tech Engineer at Sun Microsystems and Oracle, where Java was my daily business.
No matter the role, my core philosophy remains: Once a developer, always a developer. For over 20 years, I have been deeply passionate about writing robust, modern, and high-quality FLOSS code.
I am pleased to share the source code for my FLOSS projects with you here on GitHub.
If you like one of the projects below, give it a GitHub star. I am also happy to read your bug reports and feature requests.
