Overview
I am an expert Systems Administrator. I help enterprises manage large networks of secure
infrastructure while providing high quality support to end-users. I excel in deep-dive issue
troubleshooting, complex deployments and upgrades, as well as day-to-day management of
security patches and access policies.
I’ve managed hundreds of machines and servers, kept them secure through weekly or daily updates,
and provided support to technical and non-technical users for both standard and specialty scientific
applications. I work very hard for my company and my users, and have received many awards for
my dedicated service.
