PROFESSIONAL EXPERIENCE

Confidential, Santa Clara, CA

Senior Director, Technical Operations

Responsibilities:

• Tactfully managed a team of six people, local and remote multi-site production operations staff with 24x7 on-call rotations for several hosted services including Visual Voicemail, Netwise Director (a mobile data offload application), and associated Oracle databases
• Investigated multiple cost reduction methods to improve production infrastructure costs including power audits to improve power efficiencies, increasing compute density, hybrid cloud options to provide increased capacity without ongoing cost, shutting down legacy products, modernizing, migrating, virtualizing, or encapsulating legacy services, and collapsing and consolidating older operating frameworks.
• Systematically implemented an asset management system using iTop to track production data center infrastructure, hardware, networking, application, support contracts, licensing, resource relationships, and contact information. Information searchable based on hostname, IP address, port, rack enclosure, vendor, model, serial number, Ethernet address, service contract identifier, or other freeform searchable criteria.
• Successfully managed multiple service migrations including live migration of an internal data center cross-connect service to a public service load balanced across the US; a hardware deployment move from west-coast to east-coast data centers with minimal downtime, and multiple subscriber migrations to move voicemail customers to different compute clusters.
• Managed the end-of-life of several products to ensure proper termination of mobile devices, servers, and data. Minimal server and load balancer iRules added to handle lingering protocol chatter and to prevent excessive resource usage.
• Initiated multiple vendor evaluation and analysis to upgrade an aging compute-cluster with evaluations of multiple compute-blade chassis, SAN/NAS storage, network equipment, and database vendor solutions. Worked with Dell, HP, Hitachi, Cisco UCS, Juniper, Oracle ODA, f5, A10, 3Par, Netapp, Tegile, and others. Architecture is a Redhat-based Java and JBoss-based application running on a shared NAS and Oracle 11g environment with three-way streams replication, hosted in a bare-metal environment with a uniform workload that is scalable in a horizontal manner.
• Selected by management to plan and migrate the local office to a new location and managed all the logistics to find the new location, acquire the lease, move the office to the new location and re­establish connectivity with the corporate infrastructure; consolidated and drastically reduced the operating footprint of the office.
• Transparently upgraded multiple NAS instances with very limited excess storage capacity by minimizing copies, seamlessly migrating traffic to a temporary location, allowing the vendor to perform the multi-hour upgrade, and then migrating the traffic back with virtually no loss in throughput.
• Decisively managed multiple crises through effective charting, analysis, and review of historical data to identify the origination or root causes of issues; implemented targeted monitoring and alerting to prevent future occurrences; tools include Confidential, Munin, Netflow, MRTG, SiteScope, JMX, Log4j logs.
