• Design, evaluate, and improve machine learning models and experiments, making thoughtful trade-offs between performance, scalability, maintainability, and business impact.
• Design and evolve retail media measurement and optimization approaches, including attribution, ROAS measurement, incrementality testing, causal inference, uplift modelling, and experiment design, helping advertisers and the business understand the true incremental impact of advertising.
