He is currently a Graduate Researcher in Distributed AI Systems & Agentic RL and in Robotics Software & Human-Robot Systems, building infrastructure for agentic reinforcement learning on NCSA DeltaAI and AWS while developing real-time sensing, coordinate-transformation, and robot-control workflows for 6-DOF physical experiments. Shreyash is strongest in systems work where correctness, latency, scale, and reliability must coexist: distributed training and inference, GPU profiling, Java/Kotlin microservices, REST and gRPC APIs, caching, database architecture, and observability. Before UIUC, he spent 2.5 years at Oracle building telecom and enterprise software, including telco payment-gateway systems and services processing more than 10 million transactions per day. He led a small team that built a production RAG system used by more than 500 engineers. His recent technical work includes deploying Qwen3.5-4B with PyTorch FSDP2 and vLLM on four NVIDIA RTX PRO 6000 Blackwell GPUs, debugging NCCL synchronization failures, and creating an end-to-end DeltaAI-to-AWS-to-SWE-Bench execution path for software-engineering agent workflows. ## Services -
