Created change documents, submitted to Operations for implementation, and tracked their progress.

  • A Local ISP/Managed Hosting Provider: Brought up new transit providers and provided BGP assistance as needed, and planned and led a datacenter migration. Planned and led the upgrade of several customers to MetroEthernet service; included upgrading network infrastructure and creating standardized BGP configs for those who would maintain their older connections as backup. Audited and documented core network architecture and router configuration, recommended numerous improvements.

  • A Local Web Hosting Provider: Applied to ARIN for new address space; standardized rwhois data and DNS records to meet ARIN's requirements. Assisted with network design and hardware requirements for routers needing to handle several BGP feeds.

  • A Regional Transit Provider: Adapted the IP address allocation method to rwhois format in preparation for ARIN IP space application.
