I am a Mac-guy since the beginning of the Apple Macintosh, before that I used MS-DOS, MVS, VMS, VM, Cobol and others to control IBM and NEC mainframes.

At the beginning I was involved in System Operating and System Programming, later moved to Application Programming.

Spent some years using IBMs AS, the first 4th generation development language and later programmed in HyperTalk, AppleScript, RealBasic and RealStudio.

Right now my favourite tool is
XOJO, a very powerful developer tool, to compile cross-platform for iOS and macOS, Windows and Linux.

I have been a part time teacher of Cambridge Computer Science for 2 years at primary and high school level, using Linux, Windows and macOS.

I also have a Cambridge IGCSE Computer Science teacher qualification (UK), the Harvard certification "Leaders of Learning" (US) and also have diplomas as Specialist Counsellor (UK) and Meditation Teacher (US).

I'm a black belt in Judo and Kickboxing.

apps are available at the Apple App Store and on this website.
