Summary

I am 23 years old and I have been programming since I was 9. It all started because I wanted to create small Flash games. I knew about small Flash game websites and thought I had played everything on them, so I needed my own games. First, I created several websites, and once I had covered that area very well, I began programming Android apps. At first, I used Apache Cordova, but I soon found Java to be my favorite for app programming. When I thought I had reached the end of my possibilities, I discovered Alexa Skill and Google Assistant Action development.

I love to keep improving and learning new languages. Over time, I have learned more and more languages. The exciting thing about technology is that you can never learn enough. That is why it is important for me to keep growing, to take on new tasks, to realize new ideas, and to contribute to digitalization and innovation.
