I build scalable Snowflake and dbt data platforms that improve analytics reliability and cost efficiency.

I've built Snowflake and dbt data platforms for Alervio, including reusable restaurant-data ingestion patterns that doubled onboarding capacity from 5 to 10 restaurants per month.

I design dimensional models, incremental and CDC pipelines, and governed analytics warehouses using Snowpipe, Streams & Tasks, Dynamic Tables, Airflow, and dbt. My Snowflake optimization work reduced analytics processing costs by 35–45%.

At Arizona State University, I built cloud analytics pipelines for an AI chatbot application processing more than 100,000 monthly interactions. I delivered dbt models, AWS ingestion workflows, data-quality controls, and Tableau-ready marts for engagement and model-performance reporting.

Across advisory, retail, and analytics environments, I've migrated business data, built Kafka streaming pipelines, supported production SLAs, and created reliable reporting datasets. I'm SnowPro Core certified and enjoy mentoring engineers on SQL, dbt, Snowflake, and data-quality practices.
