Senior Data Analyst at Exact Sciences, building SQL reporting pipelines and KPI frameworks for commercial analytics.

Message

At Exact Sciences, I own commercial analyses from business questions through analytical requirements, datasets, KPI frameworks, and stakeholder-ready insights. I build SQL-driven ETL and reporting pipelines with Tableau Prep, Tableau, and Excel, and work with sales, reimbursement, and customer data in Databricks.

At AVON, I analyzed campaign and customer engagement data across Snowflake, Salesforce Marketing Cloud, and Salesforce Data Cloud. My A/B test and marketing automation analysis contributed to a 14% increase in email open rate.

As Global Digital Marketing Lead at AVON, I designed GA4 measurement frameworks around cross-market business needs and established tracking standards. I also trained global teams on data analysis and interpreting reporting outputs.

Earlier, at PURE PLAY and Eobuwie.pl, I analyzed AdTech and e-commerce campaign performance, attribution, and conversion data, and built Looker dashboards. In selected projects, I created SQL workflows for combining data from PDFs, images, and Excel files, then analyzed and visualized it in Metabase.
