Message

At Colaberry, I create Power BI dashboards for HR, Finance, Sales, and Operations case studies, using DAX and Power Query to prepare and explore the data. I also assemble ETL workflows from REST APIs, SQL Server, spreadsheets, and CSV files.

For my Sales Analytics capstone, I studied more than $50M of simulated revenue to examine product sales, customer behavior, and revenue trends. I also produced an HR analytics dashboard for attrition, workforce changes, and diversity.

Previously, at Cottonwood Financial, I analyzed loan, sales, customer, and financial data and built dashboards and reports for management. Before moving into data work, I ran Sales, Marketing, and Operations at KAD Construction PLC, where I introduced KPI frameworks and Excel reporting and cut operating spending 20% through data-backed process changes.
