PROFILE

Yanli Zhao

Yanli Zhao contributed to core PyTorch repositories, focusing on distributed systems and model optimization. Over four months, Yanli built features such as a configurable DDR memory parameter for shard_quant_model inference in torchrec, improving CPU memory utilization for memory-constrained deployments. In pytorch/pytorch, Yanli enabled dynamic DDP bucket order rebuilding to optimize distributed training when unused parameters are present. For FBGEMM, Yanli developed a new C++ API for direct key-value storage in EmbeddingRocksDBWrapper, streamlining embedding workflows. Across these projects, Yanli applied expertise in C++, Python, and database integration, delivering targeted, well-integrated solutions that addressed specific performance and deployment challenges.
