Hi, I'm Merve 👋

M.Sc. Data Science student at Dokuz Eylül University, working on both sides of applied AI: LLM systems (agents, RAG, evaluation) and classic machine learning (risk scoring and anomaly detection on imbalanced data). My thesis is on the statistical evaluation of open-source LLMs with LLM-as-a-Judge. I like building things end to end: the model, the API, and the tests that show it works.

  • 🎓 M.Sc. in Data Science @ Dokuz Eylül University (in progress, GPA 3.70) · B.Sc. in Electrical & Electronics Engineering
  • 🔬 Thesis: statistical evaluation of 7B–8B open-source LLMs (Friedman, Wilcoxon, McNemar)
  • 💼 AI Model Evaluator (RLHF) @ Outlier AI, part-time
  • 🧪 AI & Computer Vision Engineer @ Glossa, an early-stage startup project (12/2025 – 07/2026) · 1st place, LLM Jetpack Ideathon
  • ⚡ Former project engineer in solar energy
  • 🌍 Top 10, EU-funded E-DATA Project (study tour in the Netherlands & Germany)
  • 📫 Open to junior AI Engineer and Data Scientist roles (EU or remote) · EU citizen
