Introducing Bootstrap 4

Jörg Krause has been working with software and software technology since the early 1980s, beginning with a Sinclair and taking his first steps as a programmer in BASIC and assembly language. He studied Information Technology at Humboldt University, Berlin, but left early, in the 1990s, to start his own company. He has worked with Internet technology and software development since the early days when CompuServe and FidoNet dominated. In 1998, he worked on one of the first commercial e-commerce solutions, and wrote his first book in Germany. Due to its wide success, he started working as a freelance consultant and author in order to share his experience and knowledge with others. He has written several books with Apress, Hanser, Addison Wesley, and other major publishers along with several self-published books-a total of over sixty titles. He also publishes articles in magazines and speaks at major conferences in Germany. Currently, Jörg works as an independent consultant, software developer, and author in Berlin, Germany. The main focus is Web development (nowadays called full-stack), cloud native architectures, and Web security. In his occasional spare time, Jörg enjoys reading thrillers and science fiction novels, and going on a round of golf.
