PROFILE
Mert Hidayetoglu
Mert Hidayetoglu contributed to JetBrains/ArcticInference by engineering distributed inference features for large language models, focusing on scalable multi-GPU deployment and performance optimization. He implemented distributed sequence and shift parallelism, enabling efficient model execution across devices, and integrated CUDA kernel development to support custom operations. His work included optimizing attention mechanisms, refining model shape capture for flexible deployment, and supporting Mixture of Experts models with robust input/output handling. Using C++, CUDA, and Python, Mert addressed both feature development and bug fixes, demonstrating depth in distributed systems and GPU computing while improving documentation and maintainability throughout the project’s evolution.
