PROFILE
Yexiang-aws
Worked on high-performance networking and reliability improvements across two repositories over a two-month period. In aws/aws-ofi-nccl, upgraded the NCCL network stack to version 2.24.3 and extended the plugin interface with ext-net v9 API support, enabling NIC fusion, virtual NICs, and improved transfer size management for both point-to-point and collective operations. For ai-dynamo/nixl, focused on robust error handling in Libfabric integration by implementing indefinite retries with exponential backoff and periodic logging, reducing manual intervention and increasing throughput under load. Leveraged C and C++ for system and network programming, emphasizing API development, error handling, and performance optimization.
