Dominik Pataky

Hello! My name's Dominik, also known by my nickname cookie and handle bitkeks. In short, I'm a politically committed European citizen and an IT professional.

Me

Professionally, I'd define my field of interests in the area of IT security with focus on networks, as well as programming with an emphasis on stability. 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 other things occuring in daily life.

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). This project allowed me to gather a lot of experience with business models, team management, B2B cooperations as well as IT compliance.

IT & Software

My main focuses in IT are privacy, data analysis, networking and distributed systems, security and virtualisation. Over the years I have contributed to many software projects, or created my own. I am for example the creator and maintainer of the netflow package on PyPI.
