Financial BI Analyst and ACA turning SQL and Power BI into executive financial insights.
NigeriaWhat I'm looking for
I’m a Financial BI Analyst and Chartered Accountant (ACA) with 4 years of experience turning financial data into executive insights. I build Power BI dashboards, SQL reporting solutions, and Excel automation to improve revenue visibility, strengthen forecasting, and support strategic decision-making.
I specialize in Power BI (DAX, data modeling, dashboards) and SQL reporting, using Power Query, ETL, and data cleaning/transformations to deliver reliable reporting. I also apply KPI reporting and data storytelling through exploratory analysis to make trends actionable for leadership.
In my recent work, I’ve designed automated Excel receivables integrating billing, collections, payment status, and aging analysis, and coordinated VAT and Withholding Tax compliance for 5+ corporate clients. I also built Power BI dashboards for transaction analytics and investor-facing forecasts, and I’ve delivered SQL + Power BI projects like revenue leakage analysis and KPI dashboards that reduce reporting effort and speed up executive visibility.
