About

ML Inference Systems Engineer at Trendyol, where I build the platform serving 1M+ requests per minute to 100M+ customers — recommendation, search, and increasingly AI agents in production. My work sits at the intersection of ML, systems, and infrastructure: vLLM and Triton for serving, Kubernetes across cloud and on-prem, and Piper, our in-house orchestration system for the deployment lifecycle. I care about the parts of ML that don't make it into most conference talks — p99 latency, GPU utilization, what breaks at 3am, and how inference systems actually live once they're deployed. I co-organize GDG Istanbul, where we run monthly meetups and DevFest — one of the larger developer conferences in the region. I speak regularly at Build with AI, DevFest, and GDG events across Turkey and abroad (most recently GDG Baku). I contribute to Google's Agent Development Kit and write about production AI agents, inference optimization, and ML platform engineering. If you work on any of this, say hi.
