At Beijing Sinobridge Technology Co., Ltd. – Nanjing Branch, I supported banking, securities, and insurance clients with network design, deployment, configuration, and ongoing operations. I configured and maintained routers, switches, firewalls, and wireless infrastructure across Cisco, Huawei, H3C, Check Point, Fortinet, Palo Alto Networks, and Hillstone environments.
On CITIC Bank’s Jiangsu equipment-replacement project, I supported phased migration from aging Cisco devices to H3C equipment while maintaining network stability and business continuity. I also isolated an ICBC-AXA Life Insurance FTP transfer issue using Wireshark and resolved it by adjusting TCP MSS / Path MTU handling.
