プロフィール概要

I am an experienced technology leader and data scientist with over 15 years of international experience designing and delivering high-performance, data-driven, and cloud-based solutions across industries including telecom, finance, e-commerce, and healthcare. My expertise spans business intelligence, AI/ML, data engineering, and full-stack software architecture. Currently, I serve as Director of Business Intelligence & Data Analytics at InfiniteChoice, where I lead the development of a Universal Data Platform on Google Cloud (BigQuery, Dataflow, Pub/Sub) serving 275M+ users. I have also managed large-scale SaaS integrations and technical implementations at Starburst Data and Sumo Logic, driving adoption, API performance, and customer success across Fortune 100 clients. My technical toolkit includes Python, SQL, dbt, TypeScript, React, Node.js, TensorFlow, PyTorch, and Apache Airflow, with extensive experience in cloud infrastructure (GCP, AWS, Azure) and microservices architecture (NestJS, Kubernetes, Docker). As a PhD candidate in Cognitive Informatics, my research explores quantum cognitive models of decision-making using machine learning, Bayesian networks, and inductive logic programming. This academic foundation strengthens my ability to bridge theory and practice in applied AI and decision intelligence projects. I specialize in transforming complex data ecosystems into actionable insights and scalable architectures — enabling organizations to make smarter, data-informed decisions and accelerate innovation.
