[About]
Hello, I'm Richard.
Full-stack developer & designer · from Slovakia · Masaryk University, Brno
I understood as a child that I enjoy working with computers. At eleven I started programming backend applications. Over time I found my way to the web, where I began experimenting with design and JavaScript. My love for the web eventually brought me to cybersecurity, where I build and solve (mostly) web challenges.
