I worked as a software architect, team lead and instructor for about 20 years. In my spare time I like to write articles on the topics C++, Python and Haskell, but he also like to speak at conferences. Since 2016 I'm independent giving seminars about modern C++ and Python.
My books "C++ 11 für Programmierer ", "C++" and "C++ - Standardbiliothek" for the "kurz & gut" series were published by the publisher Pearson and O'Reilly. They are available in German, English, and Korean. In summer 2017 I started a new book at Leanpub: Concurrency with Modern C++.
I'm the author of the two well known blogs.
