Elliot is a co-founder of Chalk, where he works directly with engineering teams to transform the data and infrastructure behind their ML models and AI agents. He started his career at Affirm, where he built the early risk and credit data infrastructure system (the inspiration for Chalk). He then co-founded Haven Money, which Credit Karma acquired to power its banking products. He holds his B.S. and M.S. in Computer Science from Stanford.
Talks
- Real-time Feature Serving for Online Inference
FSS 2024
Learn how Chalk built its just-in-time online feature store to enable realistic ML use-cases and serve requests in under 5 milliseconds.
- Building Real-Time Context for Data Agents That Improve ML Models
FSS 2026
Agents need more than raw data: feature definitions, lineage, model inputs and outputs, experiment results. How a shared real-time context layer lets agents trace predictions, spot missing signals, and propose the next experiment.
