Senior Data Scientist

Responsibilities:

Dispatch ranker which optimizes long - run, risk-adjusted value instead of myopically minimizing ETA
Max-dispatchable ETA model that maximizes efficiency as a function of local marketplace conditions
Dispatch offer time-out window set via simulation model bootstrapped with censored historical data
Predictive and survival models for rider and driver-initiated cancellations during the dispatch process
Designed model-selection and smoothing technique to stabilize estimations in low-data cities
Developed causal inference model (and package) to evaluate marketplace impact sans A/B testing
Drove experimentation across many algorithmic products - dispatch, pricing, and supply positioning
Conducted analytical deep-dives into behavioral and geospatial data to drive the product roadmap
Trusted by leadership to quickly diagnose regressions in marketplace health using a data-driven approach
