Let Me Introduce

I’ve worked as a software architect, team lead, and instructor since 1999. I have been giving training courses since 2002. In 2011, I published the first worldwide C++11 book. Since then, I have published eight additional C++ books, translated into five languages.

Since 2016 I have been an independent instructor and do the job I love: learn and teach. In a typical year, I give 40 to 50 seminars about modern C++ and Python, participate in 10 conferences and provide presentations and workshops for them.
