I enjoy creating websites and applications in NodeJS (Express and Electron) and PHP.
I often read about new languages and frameworks and I have created some of my own frameworks for rapid website development (not publicly released). I also write mobile applications in Java and Google's Dart (Flutter).
I'm comfortable working with macOS, Linux (desktop and server) and Windows and take care to test my websites in multiple browsers on each platform.
