I regularly utilize managerial and customer-service skills as well as technical knowledge. In particular I have become skilled at managing projects, interfacing with customers, defining company-wide hardware and software standards, and planning for disaster recovery and business continuity.

Project Management

I have regularly led teams of up to ten participants.

I have been the sole person accompanying equipment to customer facilities in order to set up and train customers on the equipment. I have provided tech support for equipment while I was at customer facilities as well as after I returned to USA’s facilities. I have been responsible for ten sets of hardware worth half a million dollars each.

Defining Company Standards

Standards play a large part in reducing cost and improving maintainability of systems.

The standards included minimum version, life span, and, in some cases, migration path.

Disaster Recovery and Continuity Planning

I have organized disaster recovery plans for several local area networks.  The plans included items such as offsite storage, frequency of data backup, data retention, and testing the plan. Working as part of a team, I have also engaged in continuity planning including identifying critical systems, determining how to mitigate risks in case of disaster, and testing the plans.
