When Sascha Kersken was about three or four years old, he watched "Space:1999" for the first time, and some months later he started watching "Star Trek" (the original series; this was many years before his all-time favourite TNG started). From the first moment on, he knew that he wanted to defy the Final Frontier of space. Right from the start he knew that you need computers to do that, so he decided that computers (and robots) are cool.
After some detours, he made IT his profession in 1996, working both as a trainer and as a developer for the web that was still young back then. Since 2007, he's been working as a full-time employed Senior Software Engineer at a web company in my hometown Cologne.
Since 2002, he has been writing IT textbooks like the "IT-Handbuch für Fachinformatiker" (it will be published in its eighth updated and extended edition in June 2017), "Apache 2.4" (four editions so far), as well as books about Flash, MySQL, Ruby, and other admin and programming topics.
In September 2016, he self-published the German version of his first novel, "Göttersommer", after writing fiction for years but never finishing any because of time constraints. Then he created the English version, "Summer of the Gods", which was finished on December 31, 2016, then professionally edited by a native-speaking freelance editor, and self-published in January 2017.
His hobbies -- apart from computers -- are books (novels, especially science fiction and fantasy, but also many topics of non-fiction), comics (he has been reading them since he was about 7 or 8, and he actively writes and draws his own), and music (Heavy Metal, Hard Rock, Progressive Rock/Metal, and many other genres).
