A "Linux systems specialist", did claim my previous business card and did so from 2001 to May 2013. Then it said "Senior System Administrator" in another company, Stonesoft, which is part of McAfee/Intel Security. Then since February 2015, it had "Information Security Analyst at Intel Security" printed in it. And, from January 2016 it tells me "Systems Engineer at Forcepoint". Phew, all this title massage is getting heavy!
I am a certified GIAC GCIH and Zabbix 4.0 Certified Specialist.
My heart also has a place for FreeBSD.
