Raaghavendra K R developed a YANG model for the sonic-net/sonic-buildimage repository that maps Traffic Class to DSCP values, enabling accurate traffic prioritization and reliable configuration reloads in dual-tor network topologies. Using YANG modeling and Python, he defined the schema and logic to improve QoS accuracy and reduce deployment issues. In sonic-net/sonic-mgmt, he addressed a bug in BUFFER_QUEUE deletion logic by ensuring only exact interface names are matched, which enhanced data integrity and stability in interface management. His work demonstrated depth in DevOps, backend development, and network configuration, focusing on robust, production-ready solutions for complex networking environments.
