Alexey Zelenin is a Senior Network Engineer based in Melbourne with over 8 years of recent enterprise and ISP-focused experience and a career that spans large telco, emergency services, banking, and start-up networks. He designs, implements and troubleshoots complex routing and switching, data centre, wireless, DOCSIS and software-defined network environments, and has led cross-datacentre BGP and OSPF integrations and migrations. Notable work includes simplifying external connectivity for NAB across two datacentres with numerous third-party BGP peers, integrating HFC assets at Telstra, and architecting an entire DOCSIS-based ISP stack earlier in his career. Alexey blends hands-on device-level debugging (Riverbed, Wireshark) with formal design, change management and documentation practices, and is comfortable owning projects from BOM and design through audit and decommissioning. Colleagues rely on him as a calm escalation point in mission-critical deployments and disaster recovery exercises. He brings pragmatic engineering judgment informed by decades of progressively complex network architecture and operational delivery.
