At Zenith Bank Plc, I built and maintain interactive Power BI dashboards for departmental revenue, product growth, and operational KPIs. Finance and business-unit leads use them directly, and they cut manual reporting time by 30%.
I write and optimise advanced SQL against Oracle databases and designed Python and SQL ETL workflows that bring data from multiple systems into reporting-ready models. I also built API-based extraction scripts for transaction tracking and redesigned bottlenecked data flows.
At Zenith Bank Plc, I implemented validation, reconciliation, and quality checks that improved reporting accuracy by 25%. SQL-based audit data mining traced a reporting discrepancy to its root cause, helping recover NGN 100M in revenue leakage.
Earlier at Zenith Bank Plc, I worked in funds transfer and AML/KYC, creating transaction-monitoring structures and data models for risk and audit teams. In my independent Financial Crime Analytics project, I built and validated a fan-in detection method that reached ~94% account-level precision on transaction network data.
