What I'm looking for

I'm seeking to contribute my data analysis, reporting, dashboard, and data-quality skills to a forward-thinking organization that values data-driven decision-making and operational efficiency.

At Health Implementation Program (661 NAFH), I manage, validate, and maintain large datasets with 99%+ data-entry accuracy. I use Excel-based checks and SQL queries to reduce errors and support reliable departmental reporting.

I've built Power BI KPI dashboards, automated Excel reports that reduced manual reporting time by about 30%, and performed exploratory analysis to identify patterns and anomalies. I also apply Python, R, SQL, and basic machine learning to improve reporting and decision-making.
