I have been working in IT for 23 years, serving clients ranging from the Girl Scouts of the USA, Cherry Lane Music (now BMG), Halcyon Asset Management (now Bardin Hill Capital) and Mark Gould Architect (since 2008). These networks, large and small, encompass Windows and Mac domains, virtualization, mobile devices, email/messaging, PBX/VoIP, security, firewalls/switches/APs, and compliance.  I aim for five 9s of business uptime and traffic optimization that allows 3D rendering to be done on server storage, without business interruption or staticky/dropped VoIP calls!
