Hello!

Welcome to my homepage.

I love writing. That is, articles, apps and books. Also, I am a confessing mobile computing addict. And you can frequently watch me speaking at conferences and meetups.

Being a child of the 70s my first encounter with programming was in the era of home computers. Those tiny machines (mine was a Laser 210) were usually fed with BASIC, which was the first programming language I learned. Later came C, Perl and a few more. During the 90s I wrote a bunch of programs for the Atari ST series. I was so proud of my TT.

The first decade of my professional career was (inevitably) Java. Today it’s mostly Kotlin, C#, Dart and Swift.
