I've built data platforms for Essor, Amazon Devices Finance, and MatchMove Pay, turning finance, advertising, logistics, and transaction data into reliable products. At Essor, I built a SKU-level profitability platform across 20+ brands and improved reconciliation accuracy from 92% to 98–99%.

I've modernized legacy systems, migrated 100+ API integrations to AWS and Snowflake, and automated data workflows for payments and finance. I work across Python, SQL, AWS, Snowflake, Redshift, and Airflow to deliver scalable ETL/ELT pipelines, data warehouses, and reporting datasets.
