I build production data models and self-serve tools that turn contractual complexity into business value.

At Sennder, I own warehouse models for the freight scaleup's highest-revenue account, translating custom contractual logic into production data products built with dbt and Snowflake. I built a GPS-trip-record product valued at C360K+/year that replaced a manual carrier email loop and made previously unproven contractual penalties claimable.

I've migrated business-critical spreadsheet processes into tested Fivetran and dbt flows, built Streamlit tools and Looker reporting for non-technical stakeholders, and operated models in Dagster across Kafka and operational data sources. Earlier, at Epta and Hilti AG, I turned customer, sales, portfolio, and market analysis into commercial recommendations and reporting.
