Before that, he was CVP of the Cloud AI Platform at Microsoft, according to his LinkedIn profile. In that role, he oversaw Cognitive Services, Bot Framework, Machine Learning, Azure Search and more. And before that, he was Corporate Vice President of the Data Platform at Microsoft, where he was responsible for databases, big data, machine learning and information management.
