About me

I am Robert, professionally a so-called "Full Stack Developer" in the area of .NET and Web and have been working in IT for more than 10 years. I originally started out as a programmer around 2011. After I’ve worked for several small and big companies in the past years, I’m self employed nowadays. In addition to IT – which turned from a hobby into a profession – I would describe my penchant for the stock market and my interest in psychology as my (further) hobbies.
