Wayne is ready for their next project!
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.

Designed, built, and supported production ETL pipelines that integrated data from multiple operational systems into Snowflake. I used SQL, Matillion, APIs, and automated workflows to transform and validate data, implement quality checks and exception handling, monitor scheduled jobs, troubleshoot failures, and deliver reliable data for reporting and analytics.

Built an AI-powered analytics solution in Snowflake using Cortex to give business users natural-language access to trusted operational data. I created semantic models, verified queries, business rules, and curated views, then organized multiple Analysts under a single Agent so users could ask questions across different subject areas and receive governed, consistent answers.

Built data-quality and reconciliation processes to identify discrepancies across operational and reporting systems. Used SQL and Snowflake to trace records through source-to-target logic, isolate data issues, validate business rules, and create repeatable checks that improved confidence in downstream reporting.
