Semi-retired (age 75+) I'm a website-developer (especially video stuff, using "video-js") I'm also a java-lover/developer I've built a few native Android apps (using Android Studio and Java)

I'm a strong advocate for Open Source Software: https://en.wikipedia.org/wiki/Open-source_software [ So, I bundle my JS and CSS into the HTML-file, for visibility for others ] [ And, for mobile devices, I use Google (Android) rather than Apple. ]
