As a passionate developer who started to code with Pascal and BASIC in the 1980s, and then used Prolog and C++ in the 1990s, Java, PHP and JavaScript in the 2000s, he increasingly learned to love JavaScript for its unique blend of OO, functional and dynamic programming. He started the web-engineering.info platform for the learning developer, where he only recently published the tutorial books “Building Front-End Web Apps with Plain JavaScript” and, jointly with Mircea Diaconescu, “Building Back-End Web Apps with Java, JPA and JSF”. He has studied Mathematics, Philosophy and Informatics in Heidelberg, San Francisco and Berlin. Since 2004, he is Professor of Internet Technology at Brandenburg University of Technology, Cottbus, Germany. His research interests include modeling and simulation, foundational ontologies, and knowledge representation. He has more than 150 publications in these areas in international journals and books, 37 of which have been cited at least 37 times (according to Google Scholar).
