Built regular sales and KPI reports on stock levels, product performance, and seasonal demand, flagging data discrepancies before they reached management.. Monitored inventory and sales data daily and surfaced emerging demand trends to the purchasing team, cutting both stockouts and overstock in high-velocity product lines.. Maintained data accuracy and integrity across thousands of active SKUs while coordinating stock receiving and backroom organisation — high-volume, low-error-tolerance work that data validation is built for.. Presented findings in plain language to department heads and buyers, translating sales data into shelf placement and aisle-flow decisions — regular practice across technical and non-technical audiences.

Handled high daily transaction volumes with consistently low till-reconciliation error rates — the same attention to accuracy now behind every data validation check.. Worked directly with point-of-sale reporting and end-of-day reconciliation, an early introduction to operational data tracking.
