Nikolaos Markakos
German Teacher · Author · Mechanical Engineer (NTUA) · Website & Digital Content Manager
Mechanical Engineer from the National Technical University of Athens, German teacher and author with more than 15 years of experience in language teaching, language assessment and the development of educational material. My work combines linguistic accuracy, structured analysis, research, digital content and AI-assisted workflows.
About me
Since 2010 I have worked professionally in German-language teaching, with a particular focus on grammar, written and oral language assessment and preparation for Goethe examinations. Since 2012 I have worked independently, teaching levels A1–C1 in private lessons, small groups and online. To date, I have taught approximately 150 students.
I am the author of the four-volume series “The Grammar of the German Language”, published by DbM. Volume I has been published (198 pages; ISBN 978-618-83943-0-8), while Volumes II–IV are in an advanced stage of writing and editing and are already used in the teaching process.
My engineering background includes technical studies, occupational health and safety documentation, legislation research, technical offers and structured technical documentation. This background has strongly shaped the analytical and verification-oriented way in which I approach language, content and information.
