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.

Jörg Krause自1980年代初開始從事軟體和軟體技術工作，最初使用Sinclair開始他的程式設計師生涯，使用BASIC和組合語言進行編程。他在柏林洪堡大學學習資訊技術，但在1990年代初期就提前離開，開始創辦自己的公司。他從互聯網技術和軟體開發的早期時代開始工作，當時CompuServe和FidoNet佔據主導地位。在1998年，他參與了其中一個最早的商業電子商務解決方案的開發，並在德國出版了他的第一本書。由於廣受歡迎，他開始擔任自由顧問和作家，與其他主要出版商如Apress、Hanser、Addison Wesley等合作出版了多本書籍，並自行出版了多本書籍，總計超過六十本。他還在雜誌上發表文章，並在德國的重要會議上演講。目前，Jörg在德國柏林擔任獨立顧問、軟體開發人員和作家。他的主要專注領域是網頁開發（現在稱為全棧開發）、雲原生架構和網頁安全。在偶爾的空閒時間，Jörg喜歡閱讀驚悚小說和科幻小說，並打一場高爾夫球。
