Summary
Senior Data Scientist at Uber for the past 5 years, working in Earner Access. I specialize in A/B testing, Causal Inference, and Synthetic Control.
I work in an embedded Product team, directly with Senior Product Managers, Senior Engineers, and Tech Leaders, and I have produced dozens of proactive analyses with bespoke metrics that I have developed end-to-end.
My analyses have driven business decisions that have saved tens of millions of dollars for the business, and led to double-digit percentage improvements in the Uber Earner Onboarding funnel.
I have ultimately presented this work to executive leaders, external stakeholders, and Staff+ level Science experts at the company.
