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, and am now part of a team which aims to found a startup based on the results from multiple theses (focus on security on the Kubernetes platform). Besides technology and software development, my interests include philosophy, history, environmental protection and politics.

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