To whom it may concern,
I was the supervisor of Boyi Zhang when he worked for XXXX company. He performed as an outstanding System and Network Administrator and I would really highly praise him.
During his 6 years (From July 2005 to Sept 2011) with me, he did good jobs in the following fields:
1, Maintained a Nation-wide Microsoft Active Directory and Microsoft Exchange Mail System, which has 45 sites around China;
2, Managed the core node in Beijing, EMC and IBM SAN Storage System, IBM Tape Library, Brocade Fabric Switch and more than 50 PC Servers;
3, Managed Microsoft SQL server Databases, VMware ESX virtual servers, Monitoring tools, Anti-Virus tools and so on;
4, Coordinated with the leaders and workmates to make working plans, be responsible for the daily operation ,make system upgrade programs.
In all, I think he could act perfectly as a System and Network Administrator.
Yours Sincerely
