Dawis

alias David Duong

guitarist · programmer · jazz bassist

I’m currently studying Applied Informatics in Prague and during my free time, I try to build software projects. My interest in coding started with a simple curiosity - about how my favorite games were made. This eventually led to me writing my own Minecraft mods and exploring Java development.

When I'm not at the desk, I play classical guitar or practice jazz bass with my band. Music and software have a lot in common - they both rely on a solid set of rules. But once you know your way around the system, you can get pretty creative with it.
