What I'm looking for

I’m looking to build analytics and dashboard products that help teams make time-sensitive decisions. I want roles where I can design clear reporting narratives, standardize data workflows, and expand into backend and data science work alongside real business stakeholders.

I turn high-volume sales and operations data into executive reporting, starting with my Power BI dashboards at Euro Mega Atlantic Nigeria Ltd in Lagos. I built interactive, drill-through storytelling views for sales performance across Nigerian states, standardized Excel templates across 5+ sales teams, and analyzed sales trends, inventory movement, and profitability to support stock allocation and cost-saving decisions.

Most recently, I delivered geospatial sales intelligence for CWAY Integrated as a remote contract, architecting a single source-of-truth Power BI dashboard with regional drill-down so managers could self-serve insights. Before analytics, I worked as a Clinical Assistant at Oak Healing Balm Hospital and Babcock University Teaching Hospital, where disciplined data documentation and record accuracy shaped how I validate information.
