I've worked as a software architect, team lead, and instructor since 1999. In 2002, I created a further education round at my company. I have given training courses since 2002. My first tutorials were about proprietary management software, but soon after, I began teaching Python and C++. In my spare time, I like to write articles about C++, Python, and Haskell. I also like to speak at conferences. I publish weekly on my English blog https://www.modernescpp.com and the https://www.grimm-jaud.de/index.php/blog, hosted by Heise Developer.
Since 2016, I have been an independent instructor giving seminars about modern C++ and Python. I have published several books in various languages about modern C++ and in particular, concurrency. Due to my profession, I always search for the best way to teach modern C++.
My books "C++ 11 für Programmierer ", "C++" and "C++ Standardbibliothek kurz & gut" for the "kurz & gut" series were published by Pearson and O'Reilly. They are available in German, English, Korean, and Persian. In summer 2018 I published a new book on Leanpub: "Concurrency with Modern C++". This book is also available in German: "Modernes C++: Concurrency meistern".
