At Freelance, I built a Power BI reporting system that saves two weeks of manual reporting each month and gives the team faster visibility into sales, inventory, and marketing performance.

I also analyzed e-commerce transactions with market basket techniques, helping improve online product recommendations and drive an extra £200,000 in quarterly sales. My sales and customer analysis supported pricing changes, targeted campaigns, and a five-year regional sales forecast.

At Newrest Nigeria EPZE, I used financial analysis and cash-flow forecasting to unlock ₦625,000,000 (£300,000) in working capital. I also built a Power BI supplier-performance report that saved 15 hours of manual review each week.

Earlier, at Montaigne AH Limited, I analyzed retail operations to help reduce risk by 25% and prevent £100,000 in losses. At KPMG Professional Services, I supported statutory audits through data validation, audit working papers, and IFRS disclosure checks.
