PROFILE

Qi Wang

Over three months, contributed to ai-dynamo/dynamo by building and optimizing multimodal embedding cache systems, enhancing throughput and memory efficiency for large-scale AI workloads. Leveraged Python, C++, and Rust to implement LRU and asynchronous caching, BLAKE3 hashing, and robust error handling, while integrating CUDA for GPU memory management. Improved developer experience through IDE integration, type safety, and streamlined CI workflows. Expanded test coverage and benchmarking capabilities, introducing YAML-driven workflows for reproducible performance evaluation. Addressed stability and reliability by fixing memory allocation issues and refining cache loading logic, ensuring consistent performance across vLLM, TRT-LLM, and related multimodal processing pipelines.

February 2026 highlights: Delivered a unified Multimodal Embedding Cache across vLLM, TRT-LLM, and PD workers with a dedicated MultimodalEmbeddingCacheManager, enabling memory optimizations and faster throughput within prefill/decode workflows. Expanded embedding cache coverage to PD, vLLM, and EPD paths; introduced encoder cache usage and cross-node aggregation for embeddings. Launched a Multimodal Benchmark Toolkit to evaluate image/text workloads with synthetic data. Strengthened developer experience and code quality with IDE go-to-definition support, a worker factory pattern, type safety improvements, streamlined tests, and CI hygiene (static checks, reduced log noise). These efforts improve throughput and time-to-first-token, reduce memory footprint, and create a scalable foundation for future multimodal workloads.
