  SUMMARY OF EXPERIENCE 

  24 years working in the computer industry 
              
  o  18 years working with mid-range systems, clusters, storage,
     and SANs, doing configuration planning and implementation,
     troubleshooting, system administration, and performance
     analysis and optimization:

      -  Over 5 years as an independent consultant, doing 
         disaster-tolerant cluster configuration planning 
         and implementation, system and I/O performance analysis 
         and tuning, troubleshooting, cross-platform porting, 
         operating system kernel-level programming, training
         and mentoring, and general system administration 

         Built a long-distance (130 miles) disaster-tolerant
         cluster, and took it through workload growth of a
         factor of 24X over 4 years (doubling in peak load
         every year for 3 years, then tripling the 4th year).

         Provided consulting assistance in building several
         other disaster-tolerant clusters, working with storage
         based on SCSI, Fibre Channel SANs, and CI; and utilizing
         Gigabit Ethernet, DS-3, and ATM inter-site links.

         Studied operating system source code listings to
         understand behavior of distributed lock manager (DLM)
         code and wrote assembly-language programs to modify
         operating system data structures to control lock
         mastership and reduce locking performance problems.

         Developed scripts to monitor disk performance for
         anomalies, and to check RAID-1 arrays for data
         integrity

         Investigated the feasibility of using VIA-compliant
         interconnects such as ServerNet II and InfiniBand
         as cluster interconnects for OpenVMS Clusters

         8+ years as a Digital employee: 

         *  Nearly 1 year delivering consulting in the areas 
            of disaster-tolerant clusters, cluster performance
            analysis and tuning, system and I/O configurations,
            and system administration

         *  2+ years in Storage Engineering working on RAID 
            software and providing consulting expertise for 
            the FVS30/60 and HS1xx/HS2xx/SWXNA FDDI Storage
            Server projects 

         *  2 years as a developer in VMS Engineering, working 
            on VMS Cluster code during the VAX-to-Alpha porting 
            period, maintaining the Connection Manager code, 
            and spearheading the early research work which 
            eventually resulted in SCSI Cluster support in VMS 

         *  1 year in VAXcluster Systems Engineering, 
            introducing FDDI cluster support, helping develop 
            long-distance and disaster-tolerant VMS Clusters 
            (Multi-Datacenter Facility, later renamed BRS, and 
            which has now become DTCS) and doing advanced 
            development work on RAID technology and FDDI 
            storage servers 

         *  2+ years supporting VMS, clusters, DECnet, and 
            layered products on the hotline at the Colorado 
            Customer Support Center (CSC) 

      -  5 years as a cluster system administrator before 
         joining Digital 

  o  6 years working with a variety of other vendors' 
     equipment, mostly doing programming in Cobol, Fortran, 
     and various assembly langauges
