Rockstar🎓
Top SchoolGyewan An is a seasoned network and systems engineer with 10 years of experience designing and implementing SDN, MSA (Kubernetes), and mobile edge computing solutions for large telecom environments. At Samsung Electronics he built automated SDN workflows, Ansible/AWX integrations, and device auto-configuration services for OpenStack/k8s and 5G network functions, blending hands-on controller work (ONOS) with DevOps toolchains. His open-source contribution to ONOS—implementing a Cisco Nexus REST driver and link discovery—demonstrates practical expertise in device integration within a prominent SDN controller. He also has production experience with SDS (Ceph), Bluetooth application development, and wireless infrastructure design, reflecting a full-stack networking focus from radio to cloud. Comfortable in both research and production settings, he pairs a master’s in computer engineering with a habit of delivering repeatable automation for complex network operations. A detail that sets him apart is his cross-domain fluency: he translates low-level network protocols into scalable orchestration workflows that operators can run at scale.

Contributions summary:Gyewan implemented a Cisco REST driver for Nexus 900 series switches, focusing on link discovery functionality. This involved writing Java code to parse LLDP neighbor data from the devices and build link descriptions within the ONOS framework. They also made refactoring changes to the AbstractNetconfSession and added a REST API for invoking workflows. These changes show a contribution to device integration and control within the ONOS SDN controller.
