Experience

• Primarily worked OnPrem with an Isilon/PowerScale cluster of several Petabytes (and several Petabytes of NetApp) supporting Slurm clusters. In this position (unlike IHME) I didn't work directly with the cluster software. We also had Xen XCP virtualization environments with Nimbus storage. For backup/restore: I did restoration of data files from Rubrik (cloud backup/restore) and managed tapes (LTO-9 Libraries, on-prem backup/restore). Additionally a little cabling (1GB-100GB networks), server installation/reconfiguration (e.g. 10 Tesla GPU card servers) in data center, misc SysAdmin work (mostly Linux but some Windows Workstation and Server).

• Morgan Stanley acquired Eaton-Vance March 1st 2021 but Jan 1 2022 is when all employees became direct employees of Morgan-Stanley. I was among those laid off December 2022. During mergers I continued on in the Parametric division doing several application and services releases per week to Production as well as other support work in Parametric and Eaton-Vance divisions. I was also trained on Redhat's Kubernetes implementation: OpenShift.



• Eaton-Vance acquired Parametric Portfolio January 1st, 2020. Joined EV System Reliability Engineer team.



• System Administration and Application interconnect roles primarily.



• IHME features hundreds of servers and VMs, petabytes of storage and redundant networks. Personal Highlights: I led Stornext upgrades: 5.1-6.0, I built our Sensu monitoring infrastructure (including a REDIS backend) on VMware. I created a special file store for sensitive data. I’ve built tensorflow and rancher/docker environments for development teams. I work on most aspects of IT infrastructure support. Our cross-trained teams main tasks include building and maintaining: • Petabytes of storage: Quantum Stornext,+NetApp (2.3PB) and Qumulo (4.2PB) in 2 datacenters • OS’s: Linux (CentOS 6/7 & Ubuntu 14/16), Windows (Server 2016 & 10), MacOS X • SAN/NAS: NetApp, Cohesity (Cohesity also does Azure Storage) • Networks: Ethernet (1-100Gps), Infinband (Mellanox) and Fibrechannel (Brocade) • Clusters: Univa (Sun Grid Engine Fork) on ~450 Dell Edge server nodes running CentOS • Tapes: LTO and TK10 in Oracle SL3000 and Quantum i500 robotic tape libraries, Iron Mountain • Virtualization: Several VMware 6.5/6.7 clusters running Linux and Windows VMs • Containerization: Rancher/Docker and Singularity • Database Physical and Virtual Server Support: MySQL, Percona, MariaDB, Columnstore, REDIS • Cloud: Microsoft Azure • Scripting: Bash, Python • Web Front Ends/Load Balancers: Apache, Nginx, CloudFlare. • Primary Node Monitoring Systems: Sensu (ZeroMQ sub/pub), Grafana • Primary Network Monitoring Systems: LibreNMS and Extrahop • Primary Authentication/Authorization: Windows Server Active Directory • VPN: OpenVPN • Basic Machine Builds/Installation: Cobbler via PXE/DHCP, Kickstart, base install ISOs • Machine Orchestration, Customization, Updates: Saltstack and Ansible • CI: Git, Jenkins • Documentation, Code Control, Ticketing, Git web server: Atlassian IHME, along with WHO (UN/World Health Organization), are the main sources of reliable public health statistics around the world. IHME is based in Seattle at the request of the Gates Foundation. Show less



• Spoken Communications was a private/public cloud based Contact-Center-as-a-Service company. They are now a division of Avaya. The system is built in private data centers and AWS on 4 continents. They have real-time 24x7 requirements and use an active-active layered architecture with Blue/Green deployment. The systems we ran included encrypted PCI and voice.



• APLUW is one of the four University Research Labs established with the US Navy during WWII. The IT team I led supported computing infrastucture: labwide, medical (ultrasound), DOD projects, marine research (e.g. Seaglider, Autonomous Underwater Vehicle and the machine shop that built them). etc. APL/UW appears in the novel "Agency" by William Gibson. Set, in part, during my time there. I did targeted work with research and classified computing as time and need allowed. I held a clearance for some years. My security duties required working with UW CISO office, the local NCIS and FBI offices and being a backstop admin for classified computing. Responsibilities Included: • Maintained Firewalls (ip tables), VPN and encrypted intranet tunnels (OpenVPN). • Elimination of cleartext passwords for security. • Standardized departmental printing (lprng/postscript later ipp/postscript). • Programming in C, Fortran, Perl, bash, R. • Server revision and change control using Ansible and Git. • Managed KVM server virtualization (we also used Xen and Vserver). • Built and managed apl.uw.edu DNS domain (bind), APL had redundant DNSsec servers. • Built and managed email (sendmail, postfix, exim) for apl.uw.edu domain. •Sysadmin for redundant financial database servers (Ingres, MySQL). • Standardized web services to LAMP (Linux, Apache, MYSQL, PHP) when practical, • Managed server and network monitoring (BigSister then Nagios). • Added building sensors (HVAC, Cryogenic Ice Lab) with automatic alerts. • Moved from multiprotocol network to pure TCP/IP. • Installed and maintained a web-based multi-building security camera system. • SunOS to Linux Migrations (Debian, Ubuntu) for infrastructure servers. • Converted "Servers sitting around on tables" to multiple racked server rooms. • Added Google Two-Factor for secure authentication. • Forensics Show less



• Biostatistics is the application of statistics to biology and medicine. For the first ten years I was the entire computer support staff, later we hired a junior sysadmin. I (or in some cases: we) introduced MS-Windows, Unix/Linux, email, TCP/IP, ethernet, cluster computing, RISC. My responsibilities included: • Unix administration: IBM AIX, IBM AUX [SIC], SunOS/Solaris, BSD 4, Linux. • Hardware: Intel and SPARC (SPARC servers are now Oracle Hardware). • PC administration: DOS 3, then WIndows 2, Windows 386, Windows 3.11, NT all with ethernet. • Programming in C, Fortran, Perl, tcsh, S. • Built and managed biostat.uw.edu DNS domain (bind). • Built and managed email (sendmail, postfix) for biostat.uw.edu domain. • Introduced web services to School of Public Health (Apache). • Managed server and network monitoring (homegrown). • Introduced Cluster Computing (homegrown, Condor, MOSIX) • SunOS and IBM AOS [sic] to Linux Migrations for infrastructure servers. • FIrst SPARC workstation in Seattle (Sun 4/110 pre-release OS: 3.2S), we eventually had dozens. • First port of an IMAP server to SunOS (UW IMAP) and 'pine' mail client. • Capture of computer thief Avram Morar (with University Police). • Designing computer lab networks and remodels. In UW Biostatstics we went from CP/M, VMS and TOPS-10 to MS-Windows (workstation and server) and Unices during this time. Networking started with serial lines then ARCnet then Ethernet (thick coax through Cat-5e); some of those lines I pulled personally. This was also my first exposure to supercomputing (San Diego SuperComputer Center) and virtualization (IBM VM/370 on IBM 3090 hardware) but only as a user at the time. I passed the Biostatistics degree qualifying exams at masters (and above) levels as part of my graduate school work in Quantitative Ecology where I used an object-oriented variant of Fortran to model fresh-water plankton population dynamics under Malathion stress.
