I am a self-taught software developer from Zlín, Czech Republic. I started programming in 2015 when
was studying Technical
Lyceum on high school in Zlín. The language I chose at the time was JAVA,
I wanted create apps for my Android phone. This was reason I started learning programming. I wanted
create apps that will be more suitable for me and share it to the world with Google Play. After I
developed some Android apps I wanted to make web version of it, so I started learning to develop web
applications. At first they were simple application created with HTML, CSS and some
