Bio

Formerly CTO @ Bandit ML, a machine learning API that makes decisions to optimize for long term metrics (e.g. ecommerce product recs that increase LTV). I'm a former tech lead at Twitter, where I built internal analytics services and supported ML engineers. Before that, I was an early engineer at tenXer, an engineering analytics startup that got acquired by Twitter.
