LanceDB Geneva Feature Engineering
Documentation for Geneva, a feature engineering framework for transforming raw data into features for AI models. It supports distributed processing and user-defined functions (UDFs).

Head of Delivery & Solutions at Botpress; before that, founder & CTO at Okam. And yes, agents built most of this site: left to my own hands it wouldn't exist. Left to the agents, it ships.
