Dr. Haris B.に依頼

Greece

Optimization & Geospatial Analysis Expert | Mobility, Simulation & Spatial Intelligence for Real-World Impact

プロフィール概要

I'm a data science and optimization expert with deep experience in mobility modeling, spatial analytics, and operational research. My work focuses on transforming complex spatiotemporal data into actionable insights and automated decision systems, especially for urban transportation and mobility, and people flow dynamics. As Head of Modelling & Analytics at a fast-moving startup, I lead the development of AI-powered optimization solutions using real-time data from IoT sensors. I’ve built end-to-end systems that combine routing algorithms, resource allocation models, and simulation engines — deployed via secure APIs and cloud-native infrastructure.
