I build machine learning, AI, and business intelligence solutions from data to deployment.

I've built end-to-end machine learning and AI applications, including a purchase-intent prediction system with SHAP explainability and a YouTube lyrics and album analysis agent integrating external APIs and large language models.

At Doğuş Teknoloji, DenizBank, and OBAMIND Teknoloji Hizmetleri, I developed Power BI dashboards, optimized SQL reporting workflows, and helped reduce manual reporting effort by approximately 40%.

I've also fine-tuned YOLOv11 for suspicious-activity detection, built computer vision tools with Streamlit and OpenCV, and contributed to a gaming platform using Spring Boot, React.js, Node.js, and MongoDB.
