One-third of the Operations Team responsible for deployment and management of multi-site infrastructure for the FABRIC Testbed (www.fabric-testbed.net), an NSF-funded scientific instrument for computer science research. Operationally, FABRIC uses Dell PowerEdge/PowerVault servers and storage, enhanced with NVidia GPUs, Xilinx FPGAs, and Mellanox ConnectX-based SR-IOV NICs to deliver an OpenStack-managed platform to researchers across hundreds of participating universities from Europe to the US to Japan. The networking infrastructure includes two 400Gb/s rails built across dedicated L2 and L3 links using Dell Force10, Cisco NCS and Ciena WaveServer 5 hardware.My contributions included Linux administration and solution design/engineering, all aspects of hardware deployment and maintenance, maintaining Ansible playbooks, troubleshooting complex network issues, and (using Python and BASH) developing tools for operational tasks.Rocky 8, CentOS 7, OpenStack, Ansible, Python, BASH, Cisco IOS XR, Juniper SRX, Dell PowerEdge/PowerVault/Force10, Confluence, Jira, GitHub, Ubuntu 20, IPv4, IPv6

I was the key Linux leadership for migrating an existing SAP environment (based on Power7/AIXv7/DB2) to a greenfield SAP HANA 2.0 installation on Power9+x86_64/SLESforSAPv15.Under a tight implementation schedule, I designed, engineered and delivered a reliable Linux environment including clustering and complex networking (such as per-interface routing rules and bonding over SRIOV NICs). As part of my solution, I wrote custom RPMs and created package repos, configured DNS (using BIND v9) and DHCP (using Linux dhcpd) services, designed kernel auditing, implemented centralized monitoring (using Nagios) and logging, and customized SUSE Manager to support simultaneous builds on both x86_64 VMs and Power9 LPARs.During this time, I gained considerable exposure to SAP HANA and its interactions with Linux. Additionally, I designed a MediaWiki environment for knowledge transfer.SLES/SLES for SAP 15, SUSE Manager, IBM Power9, 2-node HANA Clustering for Scale-Up, SRIOV, Nagios, Python, BASH, HMC, Dell PowerMAX, MediaWiki, AIX 7

As part of a four-person team, I provided PaaS to multiple NC State agencies, using a variety of x86_64 platforms (Dell, HP, IBM, Sun) and VMware. My responsibilities included deployment of hosts based on RHEL v2.1 through v7. Additionally, I took the lead role managing the RedHat Satellite Server infrastructure, including planning and leading migrations between versions, maintaining Kickstart profiles and updating build trees.During this time, I created many internal tools (in Python, BASH, and Perl) to automate tasks, designed and built a monitoring environment based on Nagios, and both maintained and contributed to an internal Wiki created for knowledge transfer and documentation of internal infrastructure, tools and processes. As part of this job, I participated in multiple DR/BC exercises using external vendor/remote site recovery facilities.Finally, I took on the task of engaging with RedHat to negotiate DIT’s support contracts, and to include other State agencies in those contracts. I also performed some Solaris support functions, and assisted with RHEL on IBM System Z.RHEL 2.1-7, RHN Satellite, Nagios, Python, Perl, BASH, DNS, ITIL, iLO, RSA, IMM, iDRAC, MediaWiki, Remedy

As part of an Operations Team, I implemented, secured and managed multiplatform computer networks based on based on Linux, UNIX and Novell NetWare; in support of complex business and application requirements. My responsibilities included many aspects of system management, such as hardware, IAM/PAM and storage; I also planned and led major NetWare upgrade efforts.While in this role, I designed custom electronic mail security solution using sendmail and MIMEdefang, running on SUSE Linux. I also created and maintained software configuration and tooling to meet specific business needs. As part of these efforts, I gained exposure to AIX v5 on Power5 hardware.SuSE Linux 9, NetWare 5.1-6.5, GroupWise 6.5, eDirectory, DNS, Perl, BASH, Sendmail, SpamAssassin, MIMEdefang, AIX 5

Oversaw implementation to Computerized Adaptive Testing System (CATS) environment; supervised other contract staff.

Provided expertise and services to clients.

Technology architect for NC Window of Information for Student Education (NC WISE), a project in the North Carolina Department of Public Instruction to provide a unified, state-wide K-12 student information management system.

Supervised staff, including 6-person Service Desk (contractor-staffed) and 6 full-time employees.Designed and delivered networked computing services to nearly 1K agency staff in multiple locations. Planned and led agency technology migrations, including:+ Token-Ring to Ethernet+ IPX to TCP/IP+ NetWare v3/4 to v5+ STP to UTP/FiberManaged service delivery, including:+ File and print (Novell NetWare)+ E-mail (GroupWise)+ Directory Services (eDirectory)+ DNS (BIND on Solaris)+ Phone/Telco service provisioning and changes+ Data circuit provisioningWorked with HP Proliant and Sun SPARC servers; Cisco, IBM and Bay Networks equipment.

Delivered networked computing services, initially for Raleigh Regional Office (through 1994). In 1995, I transferred to the Central Office in downtown Raleigh. The technology stack consisted of Novell NetWare v3, Token-Ring, Pegasus Mail, cc:Mail; my duties included PC hardware, OS and application support for ~50 staff.
