Data Engineer | Snowflake, BigQuery, dbt | ETL Pipelines & Warehouses

⚡ I build data warehouses that run faster and cost less. One client went from a $4,000 monthly bill to $40, with query times dropping from 84 hours to 2. I help SaaS companies, agencies, and data-heavy startups move off slow, expensive setups and onto Snowflake, BigQuery, and dbt pipelines they can actually trust.

Monthly cost fell from $4,000 to $40, query time from 84 hours to 2. ▸ Built the dbt and Snowflake pipeline behind an influencer dashboard serving Nike, Under Armour, and New Balance.
