What I'm looking for

I partner with stakeholders to gather requirements and translate business needs into scalable analytics solutions, backed by thorough data validation. Along the way, I’ve optimized Tableau dashboards, embedded Power BI into SharePoint, supported ETL for datasets with 50K+ rows, improved member engagement by 10%, reduced operational costs by 10%, and increased report accessibility by 25%—while mentoring junior analysts to strengthen the team.
