Areas of expertise

Depth where modeling, systems, and measurement meet.

Capabilities are organized around the problems I solve, not arbitrary proficiency scores.

01

Product ML

Recommendation, ranking, candidate retrieval, personalized discovery, and product scoring.

  • Candidate generation and retrieval
  • Learning-to-rank and product scoring
  • Recommendation and personalized discovery
~12M monthly users reached by personalized decision systems
See personalized product discovery
02

Causal measurement

Experiment design, uplift modeling, holdouts, confidence intervals, and decision-oriented measurement.

  • A/B and factorial experimentation
  • Propensity, uplift, and treatment effects
  • Persistent holdouts and confidence intervals
~US$1M monthly incremental GMV measured against holdout
