Deployed a highly scalable data collection and MySQL warehousing infrastructure that captured 100 million interactions from 35,000 unique visitors per day.Designed database schemas, partitioning logic and fault tolerant ingestion mechanisms. Formulated SQL and ETL logic for mining user behavior, key service metrics, marketing campaign response rates, user experience and backend server performance.

Architected the operational infrastructure and wide area network for Sun's remote monitoring service (SRS), scaling to 250,000 monitored hosts across six continents. Minimized the impact of scheduled and unscheduled downtime through the use of diverse telecomm provider connectivity, paired system/network elements, automated failover and dynamic routing.Led Sun's eCommerce platform consolidation through the creation of a virtual hosting environment. Authored kernel modules, pseudo-device drivers and a system call interposition layer that enforced separation between multiple userland environments used for OS virtualization and application stacking.

Developed colocation, web hosting, media distribution and streaming video product offerings. Integrated streaming backend with multicast, layer 4-7 switching, content storage and bandwidth shaping. Identified and resolved issues such as QOS, IP address architecture, transit & peering arrangements and the translation/incorporation of system logs into billable usage records.Supported the company's sales and business development efforts by participating in client visits, road shows and industry events where significant engineering and operational expertise was required.

Designed and implemented Level 3’s Web Hosting and IP Co-location product offerings. Deployed network infrastructure, including bandwidth aggregation, monitoring & telemetry, SMTP Email Relay, DNS, and Radius across an initial fifteen data center facilities. Implemented Bandwidth Management and Metered Billing for the dedicated access and co-location products. Supported a number of crucial initiatives by developing the technical strategies for Multicast, Caching, Streaming Content Distribution and Geographic Load Balancing. Analyzed cost, functionality and performance of several competing router and switch platforms. Drove standardization efforts and realized support savings of over one million dollars per annum by organizing Level 3’s data center services into a utility model. This environment successfully decoupled application and infrastructure lifecycles, eliminated underutilized assets, consolidated development, test and production hardware and cut physical footprint in half.

Designed host and network security infrastructure for 60-site WAN with multiple paths to the Internet. Implemented commercial, public domain and locally developed firewall / IDS software arrayed across geographically distributed bastion hosts and perimeter networks.Provided DMZ, content filtering, web caching, forward & reverse proxying, SMTP and HTTP services.
