Cover image for Co-built Insulintel through From Truck
Co-built Insulintel through From Truck To Tech, LLC, an AI-powered application designed to turn complex health data into understandable, actionable insights. My work focused on the data and intelligence layer, including Snowflake data architecture, curated data models, business logic, verified queries, and Cortex-powered natural-language analytics. The project demonstrates taking a data and AI concept beyond a prototype into a working, user-facing product.
