About

I shipped some of the biggest search wins at companies like Shopify, Reddit, and Wikipedia. I integrated Machine Learning into Elasticsearch with the Elasticsearch Learning to Rank Plugin. I've written books:Relevant Search (2016) and AI Powered Search (2024). I teach two courses: Cheat at Search with Agents and AI Powered Search. I love to coach and teach others how to improve search relevance whether users are humans or agents.
