I’ve been developing software for fun and as an occupation for over 50 years. My first job was as a computer operator in about 1976. During retirement I taught myself how to develop native Android phone apps using Android Studio.

I have also developed the following software during retirement:

1. App to Automatically Convert Music to Sheet Music (documentation & examples later)
2. American Mah Jongg Game App (documentation of app development later – JLMahJongg link)
3. Sun Tracking Solar Base Controller
