John D.

I have been a full-time system administrator for over 20 years, most of which doing both consulting and being full-time employed. My focus has been on the start-up and emerging SMB businesses which requires me to be a jack of all trades. Servers, desktop, networks (switches, routers, firewalls, vpn, wan/lan), security, applications and everything in between. I specialize in helping companies grow from a few computers cobbled together to an enterprise-minded, cost-efficient, supportable, and robust infrastructure. Being able to understand and troubleshoot difficult problems under pressure is one of my strengths.
