  EXPERIENCE 

  President, Integrity Computing, Inc., 1996-present

     Worked as a consultant under my own company, 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

  Digital Equipment Corporation, 1988-1996

     Consultant, NSIS, 1995-1996

        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

     Senior Software Engineer, Storage Engineering, 1993-1995

        As an engineer, worked on host-based StorageWorks
        RAID software and providing consulting expertise
        for the FVS30/60 and HS1xx/HS2xx/SWXNA FDDI
        Storage Server projects 

     Senior Software Engineer, VMS Engineering, 1991-1993

        As a operating system developer in the Clusters &
        I/O Group within VMS Engineering, worked on VMS
        Cluster code during the VAX-to-Alpha porting period,
        maintaining the Connection Manager code, and
        spearheading early research work in SCSI-based
        clusters

     Senior Software Engineer, VAXcluster Systems Engineering, 1990-1991

        As an engineer in VAXcluster Systems Engineering, 
        introducing support for FDDI as a cluster interconnect,
        helping develop long-distance and disaster-tolerant
        cluster technology, and doing advanced development
        work on RAID technology and FDDI-based storage servers 

     System Support Specialist IV, Colorado CSC, 1988-1990

        Supported the VMS operating system, clusters, DECnet,
        and various layered software products on the telephone
        hotline at the Colorado Customer Support Center

  Computer Specialist, Bureau of Reclamation, 1983-1988

     Worked as a server and cluster system administrator and
     network administrator, and did applications programming
     in Cobol and Fortran

  Programmer/Analyst, US Army Corps of Engineers, 1980-1983

     Did applications and systems programming in Cobol, Fortran, 
     and assembly langauge

  Systems Programmer and Student Programmer, Andrews University, 1977-1980

     Did applications programming in Cobol, systems programming
     in assembly language, and firmware engineering in
     microprocessor assembly language
