At TechStyle OS, I managed end-to-end data pipelines using Snowflake, AWS, and Airflow to support reporting and analytics. I designed scalable data models and optimized ETL workflows for BI use cases.

At L’Oréal, I analyzed multi-store sales data and improved reporting workflows to inform business strategy. Earlier, at Prof Business Outsourcing, I cleaned and transformed datasets, wrote SQL queries, and built Power BI dashboards for marketplace performance.
