Zambia

Message

At Access Bank PLC, I automated Python-based reporting pipelines over Oracle and SQL Server, reducing recurring report preparation from five hours to 30 minutes. I also designed and automated Kindergarten, a customer onboarding journey integrating Python, SQL, SMS, and Power BI, which lifted accounts funded within seven days by 56.3% versus the pre-campaign period.

Previously at FNB Zambia, I built a consolidated reporting system using BI tools and SQL that improved team efficiency by 30%. My work has included Power BI dashboards, customer segmentation, revenue assurance, and credit risk reporting, including NPL and IFRS 9 monitoring.
