I'm 19 (20 this year) started using Linux with my first Gentoo server at age 16. Did my CISCO CCNA during year 11 and 12 of my high school along side another certification in IT. Used much of my time off to do unpaid work experience and was lucky enough to get experience at places like CISCO and EMC. Spent many many weekends and weeknights playing around with linux and windows servers and when i graduated school last year i found a job in IT for a small software company. I was very lucky in having a company take the risk hiring me just out of school to manage their pretty simple IT infrastructure. Over the last year ive been there i have started deploying some company products in the cloud and Ive found myself managing Linux servers and the systems to manage them. Apache, PostgreSQL, Zabbix, High availability ect...
So my question is this, would i be considered a joke at the age of 19 looking for a serious job in system administration?
How can i make my age and experience less of a factor to potential employers?
