Leonhard Zhang

Erin Leonhard Zhang leads data foundations engineering at Afresh, where ML-driven demand forecasting helps grocery retailers cut food waste at scale. She architected and drove Afresh's migration from Azure Postgres to Databricks Lakebase, running the technical evaluation, facilitating the go/no-go decision with 20+ engineering stakeholders, and executing a production rollout that eliminated custom sync code and unlocked self-service data access across the org. A full-stack engineer who gravitates toward data architecture and platform problems, Erin has spent 4+ years as Afresh's primary technical authority on data sync patterns and pipeline design, including leading the company's reverse ETL cutover from Snowflake to Databricks.
