Career History



  • Planned and executed server and storage refresh, cutting storage and Unix data center footprint in half and cutting total data center power use by one third..
  • Remediated an existing IBM storage installation that had lost an administrator. Documented configuration, improved reliability, upgraded to supported firmware, cleaned up unneeded storage allocations which enabled Tween Brands to avoid purchasing additional capacity.
  • Planned and executed migration of 5 storage environments from IBM and HP to EMC storage using VMax storage arrays.
  • Planned and executed multiple SAN fabric consolidations and conversions.
  • Successfully planned and executed the storage and Unix tasks for a large data center consolidation project. This project consolidated 5 data centers in 4 states down to 2 data centers.
  • Currently planning and executing the storage and Unix tasks for an additional large data center consolidation project. This project will consolidate two data centers from an acquired company into our existing data centers.


  • Planned and executed a data center migration from MeadWestvaco's Dayton data center to ACS's Pittsburgh data center. Migrated approximately 100 physical and virtual Unix servers on time and under budget, saving approximately 1 million from the initial project budget.
  • Implemented large scale virtualization project, reducing the physical server count from 50 to 7.
  • Implemented IBM Power6 Live Partition Mobility. This allowed us to migrate live running system images from one physical server to another without interruption.
  • Successfully planned and executed multiple off site disaster recovery tests.
  • Led an effort to turn around a poorly performing AIX client environment. Efforts included multiple rounds of performance tuning, problem root cause analysis, and implementation of scripts and tools to proactively find and fix problems. The results included a 45 reduction in incidents, improved database performance, while lowered client cost, and dramatically improved customer satisfaction. This led to an expansion in the contracted scope of work to include additional DBA staff, and supported efforts that resulted in a 7 million early contract extension.
