Profession & interests

Professionally, my current domain of work is in information security with focus on IT security, networks and infrastructure compliance, 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.

IT & Software

My main focuses in IT are networking, privacy and security, data analysis, distributed systems 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.
