Dominik Pataky

Hello! My name's Dominik, also known by my nickname cookie. In 2019 I finished my studies in computer science at the TU Dresden, Germany. Afterwards, I was part of a team which aimed to found a startup in the focus of Kubernetes platform security (spin-off financed by the German EXIST-Stipendium, starting with the knowledge from two final theses). Besides technology and software development, my interests include philosophy, history, environmental protection and politics. I like to use the slogan Humanity cannot be digitized because of my strong believe in that no technological advance will ever be able to replace our nature-based foundation as humans.

From time to time I share my experiences on my blog, it's a mix of stories about software and politics.
