Denis was a very early hire in VGW's Data & Analytics team, and instrumental in shaping our vision and execution of our strategy. And Denis built many of the key systems in DS, ML and Marketing Tech that powered VGW's huge growth. Truly the definition of a full-stack Data Scientist. The only thing more impressive than his deep, deep technical knowledge in Data Science and DS Systems is his kind and caring good nature.
