I am a software engineer from Germany supporting several different projects.
My regular job is in cyber security and corporate governance (and still actively coding :) ).

In general I do perfer Java projects to work on and I also know how to train humans on coding and software engineering in general (I own a M. Sc. in Computer Science).

In spare time I do support projects like ioBroker where you can find some adapters.
Working on open source projects can consume quite some time and any kind of sponsorship helps justifying working on such :)

Funds will mainly be used to help cover the extra time spent and - where applicable - to fund necessary hardware or appliances to help support them.
