1. Xamarin Android because I wanted to develop a native Android app and I prefer Visual Studio

2. Xamarin Forms because my new job requires it

3. UX Design because I want to improve usability of my systems

4. Software Project Management because I want to move to management

These days I try to avoid learning new technologies. I focus mostly on improving what I already know. I only learn a technology when I want to use it and there will be a benefit for using it compared to what I am already know.
