I'm an AI Research Engineer at NewMind AI, working across the full LLM lifecycle — pretraining & fine-tuning, high-performance multi-node inference, retrieval / RAG, evaluation, and agentic systems — with a research focus on Turkish and legal-domain NLP.

  • Pretrained Turkish language models on the BSC MareNostrum 5 supercomputer (6,000+ GPU-hours)
  • Brought up & benchmarked ~20 frontier model families across vLLM / SGLang and FP8 / NVFP4 / GGUF quantization
  • Built retrieval / RAG (semantic caching, late-interaction retrieval, GraphRAG) and multi-agent systems
  • Designed LLM evaluation frameworks (calibration, LLM-as-judge, adversarial benchmarks)
