Principal Data Architect, Azure @ Penguin Random House

I've been working in and around SQL for over 3 decades. I am currently working on making our business intelligence systems self-driven by using an event-based architecture. This involves providing curated data in some of the largest SQL Azure Analysis Services cubes ever built (over 6 billion records in 1 table alone). I've developed several APIs leveraging a serverless Azure architecture to provide real-time data to various internal processes and projects. Currently working on Project Dormouse; Durable select messaging queue that enables polling processes to extract specific messages.
