Plan and conduct end-to-end validation with relevant application and video systems, and support post-implementation issue resolution.
-
Co-lead secure network integration design with a security engineer and review high-level and low-level designs, network diagrams, and future-state documentation.
-
Maintain configuration records, technical findings, validation evidence, and sustainment guidance, and provide knowledge transfer to operational teams.

Active CCIE Enterprise Infrastructure certification.
-
Demonstrated expertise in enterprise routing and switching, multicast networking, packet-capture analysis, and video-transport troubleshooting.
