about me





After a professional training in BMSR Engineering, studying electronics and graduating from Hochschule Zittau/Görlitz , with a concentration in automation technology, my first job was with a small Network/PC company, DATASCRIPT-Netzker. After much initial, customer-oriented and good practice, two years later I moved to the larger company Fleischhauer Cottbus GmbH - now independently as ISIMKO GmbH - for the establishment of a network department, in the sales, planning, installation and support of LAN/WAN networks my tasks were. After another two years with Novell Netware, Windows NT and the products of 3Com, Cisco, Cabletron, etc., I was tempted to go into development. Since that time (1998) I am now working for Giesecke & Devrient GmbH as developer of communication and security systems/modules.
