Senior🎓
Top SchoolDongya Zhang is a software engineer with 14 years of experience specializing in network devices, L2/L3 routing, SDN/OpenFlow and NFV for both product and cloud environments. He has led teams and shipped production SD-WAN and distributed NAT gateway solutions at startups and at Alibaba Cloud, combining deep protocol knowledge (BGP, MPLS, OpenFlow) with pragmatic system design. Notable technical work includes low-level OpenFlow fixes to the widely used Ryu controller and inventive VPP-based SDWAN designs such as negotiable overlay links, MPLS-like label switching and TCP-session–aware encapsulation to bypass UDP middleboxes. He favors maintainable, modular architectures (keeping work in dedicated VPP plugins for smooth upgrades) and is an enthusiastic open source user and contributor with a decade of Linux experience. Based in the Changzhou-Wuxi-Suzhou area, he blends hands-on coding with product leadership and a track record of turning network research into deployable, customer-facing features.
