I've built data and business intelligence solutions at VIP Express Tourism, Nova Academy, Toby Jug Limited, and Ace International Training Centre to improve decisions, efficiency, and cost control.

At VIP Express Tourism, I developed Power BI dashboards for lead-to-deal performance, debt recovery, customer queries, and telemarketing. These solutions improved cross-functional decision-making by 30%, recovery efficiency by 25%, and query resolution time by 15%.

I also deliver analytics training in Excel, SQL, Power BI, and business intelligence, having facilitated workshops for more than 200 professionals. In procurement, I analyze spend, supplier performance, pricing, and purchasing KPIs to support cost-effective sourcing decisions.
