About the Author
Dmytro Radchuk is a software engineer from Kyiv, Ukraine. His passion for science started at a young age and led him to receive a degree in computer science from Kyiv Polytechnic University. As of today, he has deep technical knowledge and more than 8 years of experience in the field of software development for several industries and businesses. He strongly believes that the whole is greater than the sum of its parts and this is one of the reasons why the development of distributed applications has become his main specialization.
Dmytro has always supported the idea of sharing knowledge and this has resulted in Boost.Asio C++ Network Programming Cookbook, which has become his first officially published book. He believes that science will help us deal with the monotony of everyday life. When he is not exploring another facet of computer engineering, he is probably learning a new aspect of psychology, history, or the arts, which are also of great interest to him.
