BARIŞGÜLEÇ

AI & LLM Backend Engineer

Scroll

Building intelligent systems that understand, reason, and create.

AI-focused 4th-year Computer Engineering student at Kütahya Health Sciences University. Hands-on with large language models (LLMs), deep learning, AI agents, RAG, and computer vision. Proficient in Python; experienced with data analysis, Docker, FastAPI, and AI modeling. Daily user of NumPy, pandas, scikit-learn, PyTorch, TensorFlow, and YOLO. Familiar with LangChain/LangGraph and vector stores (FAISS, Chroma) for LLM tooling and retrieval. Up to date with current LLM research; comfortable with n8n for automation to build scalable systems. For the past year, I've been delivering freelance AI projects on Bionluk.
