About Sayooj Das
I am a Technical Leader (practitioner,*not* researcher) in Applied Data Science and Advanced Analytics with over 15 years of experience defining the standards for high-stakes machine learning and the business-critical data foundations that support it. I build measurement capabilities and data-driven decision-making practices where none existed — then make them stick. Three times at Amazon, I identified a strategic gap, defined the technical approach, built alignment at the VP/SVP level, and created a lasting org capability.
