Hands-on SQL proficiency sufficient to investigate and reconcile large inventory datasets independently - multi-table joins across transactional and master data, common table expressions, window functions (running balances, deduplication, period-over-period movement), conditional aggregation, date and period logic, point-in-time cost and price lookups, and multi-level bill of materials. Represent Finance Data & Systems in evaluating and shaping decisions that impact the financial integrity of core inventory-related datasets, including inventory transactions and balances, purchase orders, receiving, bill of materials, product and vendor master data, and unit-of-measure logic.
