What I'm looking for

I'm looking for analytics work where I can build Power BI dashboards, data models, and automated reporting that turn operational data into clear decisions. I value cross-functional collaboration, leadership visibility, and independent remote or hybrid delivery.

At Niger Mills Company, I built a 16-sheet Power BI and Excel OEE dashboard suite that helped improve machine utilisation by 12% across two production mills.

I turn ERP, inventory-scale, and production-log data into star-schema models and near-real-time reporting. My reconciliation dashboard sustained 98% accuracy while replacing a manual multi-day process.

I've designed and maintained 6+ enterprise Excel workbooks with 40,000+ validated formulas, and automated recurring reporting with Python and openpyxl to save more than four hours per cycle.

Alongside analytics work, I support petroleum supply and procurement at Blue Dolphin Petroleum, applying structured analysis to RFQs, quotations, vendor documentation, and audit-ready decisions in a remote environment.
