About

Professional summary

I am a data and analytics professional with more than six years of experience supporting cross-functional eCommerce, marketplace, fraud prevention, and business intelligence teams.

I work across the end-to-end data lifecycle, including data exploration, modeling, transformation, extraction, and automated reporting. My primary technical stack includes SQL, Google BigQuery, Python, Tableau, Looker, Snowflake, dbt, and Airflow.

I build executive dashboards and analytics products that help stakeholders make better commercial and operational decisions. My experience includes profitability analytics, contribution-margin analysis, break-even ROAS, conversion reconciliation, fraud and risk metrics, and marketplace performance reporting.

I have worked with high-volume data environments and have built data jobs and pipelines using BigQuery, Teradata, ETL tools, and PL/SQL. I am also experienced in gathering requirements and translating business needs into data models and BI dashboards.

I currently work in eCommerce and analytics while implementing modern data stack practices. I am comfortable collaborating with technical and business stakeholders, working independently, and applying AI-driven automation to improve decision-making and reduce operational errors.
