Hello! I am a graduate of the MSc in business informatics (FH Technikum Wien) and have been working as a systems engineer in Vienna for several years. I also have IT tuition experience in diploma theses as well as in exam preparation (HTL). I like to teach fluently in German, English and Greek. I mainly offer tutoring in: systems administration, big data, databases (PostgreSQL, MySQL), MS Office, application servers (JBoss, Tomcat, Apache), networks, OS applications (such as Linux, Windows, MacOS), web design and development, programming for beginners and hardware. I also like to teach German (as a foreign language), English (mother tongue) and Greek (mother tongue).
