Message

At DITU, I analyze digital analytics, streaming, and advertising data, using SQL in Snowflake to investigate discrepancies and turn complex datasets into business insights.

I validate data across GA4, NPAW, AVS, AppsFlyer, Google Ad Manager, and Amazon S3. I also use Python to prepare datasets and automate data quality checks.

At DITU, I developed Power BI dashboards and reporting solutions for audience behavior, engagement, content consumption, and advertising performance. I standardized validation and reconciliation practices and automated recurring reporting workflows.

At Accenture, I designed dimensional data models using the Kimball methodology and supported ETL, data validation, and reporting solutions. I also managed Adobe Analytics tagging implementation and quality assurance activities.
