• Team Lead for engineers across varying disciplines of technologies including servers, VMs, networking, CMTS, billing, video (IP and QAM delivery), etc. supporting TES pre-production datacenter facilities in Philadelphia, New Jersey, Downingtown, and Denver. • As technical environment build team lead, surpassed 2020 goal to reduce project build velocity by 20% for projects. Original target was from 47.6 to 38.1 days, the average time to completion was 29 days, a reduction of 40%, doubling the target goal.• Lead Engineer on the Cornerstone Re-IP Project. The increased growth of TES (Technology Environments & Strategy) facilities/footprint necessitated our organization to become our own production market network to communicate with the same back-office components as deployed in the field. This enables us to test and validate across many projects and disciplines TES supports in Comcast without impacting field components and our customer base. Tens of thousands of IPs changed / in progress across many projects including LSA, Volicon, NSG Pros (non-rPHY), Warehouse, Vista, Arris Plants/Devices, CMTS, EC Plants/ devices, MediaKind Transcoders, VOD QAMs, NSG Pros, vCenters/EXSi virtual machines, Sencore, cDVR, LSA, Warehouse Environment, CAP1000s, Vista, VNCRE environments, rPHY, and more in flight. Ran each subproject/worked with all separate teams to minimize/eliminate downtime, including coordination, firewall changes, configuration changes, etc. Developed code in python to scan subnets that need to be returned freedom to provide automated daily stats of how many IPs/Subnets remaining.• Led effort to install CATS (Comcast Automated Test Solution) -Comcast enterprise platform to host control and manage CPE devices efficiently - across facilities in order to support/troubleshoot our testing environments and internal customers remotely due to the pandemic.
