Arthur Suilin is a data scientist and entrepreneur with over 20 years of experience building startups, analytics products, and high-performance data systems. He founded and exited two analytics-focused companies—RusNews (sold to Mail.Ru) and WebVisor (acquired by Yandex and integrated into Yandex.Metrica)—and later led Yandex.Metrica to become the world’s second-largest internet analytics service. A hands-on engineer, he contributed to ClickHouse and won a Kaggle web-traffic prediction competition, delivering the top solution and maintaining reproducible training pipelines. His technical breadth spans ClickHouse, MySQL, MongoDB, TensorFlow/PyTorch, Python/Java/Scala, and advanced methods like Bayesian analysis and Monte Carlo. Now based in Belgrade and working independently, he combines startup leadership, product-driven data science, and low-level database expertise to tackle large-scale analytics challenges.
