Hi, I'm Izzet 👋

PhD candidate at Illinois Tech building tools that detect and diagnose performance bottlenecks in large-scale AI workloads, from deep learning training to LLM agents.

Open-source tools

  • GDSight per-operation eBPF attribution for GPUDirect Storage (PDSW'26)
  • AgentStage stages data during LLM thinking time for 1.74x faster agent sessions (IEEE eScience'26)
  • DFAnalyzer scalable analysis of multi-layer I/O traces
  • WisIO automated I/O bottleneck detection for HPC workloads (ICS'25)

Co-author of DFTracer and Recorder.
