AI / ML
Engineer

AI/ML Engineer and Senior Software Engineer with 11+ years of engineering experience, building and delivering production-grade systems across NLP, LLMs, computer vision, model serving, and cloud-based workflows.

AI/ML Engineer·Senior Software Engineer·AWS Certified MLE·M.Sc. AI

My work sits at the intersection of applied research and production engineering from LLM fine-tuning and RAG system design to model monitoring and MLOps infrastructure. I hold an M.Sc. in Artificial Intelligence (Bahçeşehir University) and am AWS Certified as a Machine Learning Engineer Associate.

Beyond technical delivery, I write about AI systems, publish open-source research, and selectively advise organisations on AI strategy and implementation.
