Hi there. I'm Thomas, a software engineerBeing a child of the 1970s, 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, the first programming language I learned. Later came C, Perl and a few more. During the 1990s I wrote a bunch of programs for the Atari ST series. The first decade of my professional career was (inevitably) Java. Today it’s mostly Kotlin. I fell in love with Android in 2009 and have been contributing to the community since then. In April 2021, I became a Google Developer Export for Android. |
