As you can see, I haven't updated this blog in quite some time! Schools in South Africa have, for some reason, switched to using mostly Delphi and the Java space grew quiet. As for my business, I moved from Java to Scala and Kotlin, especially for mobile development on Android.
Of late, I've been making use of Dart and Flutter, with a bit of Kotlin and Swift, to develop mobile applications. You can find some more information and programming tips at https://www.nofuss.co.za. As always, I'm happy to try and assist where I can!
