Summary
👤
Senior🎓
Top SchoolYan Gorelik is a Principal Engineer based in Sunnyvale with eight years of focused experience designing programmable network applications and tooling, notably as the former principal developer of the YANG Development Kit (YDK). He specializes in model-driven, data-driven, and programmability-first solutions that bridge YANG data models with Netconf, Restconf, and gNMI service providers, and has deep protocol and architecture expertise across IP, MPLS, OSPF, VPNs, IPv6, and ATM technologies. Yan combines systems-level programming in Java, C++, Python and Go with practical cross-platform engineering—shipping platform-independent installers and modernizing support for Linux and macOS. He also brings strong simulation, modeling and algorithmic skills grounded in an MS in Computer Science, enabling rigorous evaluation of network behavior and performance. Known for supporting the YDK community on Cisco platforms, he pairs open-source stewardship with hands-on consulting to help teams adopt model-driven network automation. An understated but valuable trait: he thrives at the intersection of protocol nuance and developer ergonomics, making complex networking APIs reliably usable.
