   Feb 2025 — Present · Chicago, IL, US

   As a Senior Data Analyst at Walgreens Boots Alliance, I focus on modernizing data infrastructure and building analytics solutions that drive efficiency, transparency, and data-driven decision-making across pharmacy operations and retail functions. My work centers around cloud migration, automation, and scalable data modeling to enable reliable insights at an enterprise level.I led the migration of large on-prem SQL Server datasets to Snowflake, improving system performance and reducing operational costs by 35%. I designed and maintained data marts supporting key initiatives in prescription analytics, customer loyalty, and sales forecasting, ensuring business teams had timely and accurate data for analysis.To streamline workflows, I developed dbt models for incremental transformations and automated data validation scripts using Python, reducing manual QA time and improving consistency. I built Tableau dashboards to visualize KPIs for pharmacy operations, sales performance, and compliance monitoring, giving leadership a clear view of trends and risks in real time.Data security and governance were essential to my role — I implemented role-based access controls (RBAC) and row-level security (RLS) within Snowflake and BI tools, ensuring compliance with internal and external standards. I also integrated CI/CD pipelines (Git, Jenkins) for automated ETL deployments, improving version control and development efficiency.Throughout, I collaborated with business stakeholders to define key metrics, conducted data profiling and anomaly detection using SQL and Python (Pandas), and ensured alignment with HIPAA and internal data quality standards. My work enables faster, more informed decision-making across the organization while maintaining the highest standards of data integrity and compliance.
