Welcome. I am Johann N. Löfflmann from Munich, Germany. My first computer was a C64. I have a university degree in computer science. I worked for both Sun Microsystems and Oracle as a tech engineer, and Java was my daily business for many years. Today I am working as a presales consultant for tailored IoT projects. Once a developer, always a developer. For 20+ years, I have enjoyed writing FLOSS code. Robust, modern, shiny code. Well, at least sometimes 😉
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.
