When I cut picking errors by 30% at my current site, it wasn't luck — it was tighter zone assignments, clearer pick-path signage, and holding my team accountable to a standard, not a guess. In a food distribution environment, where a mispick can mean spoiled stock, a missed delivery window, or a compliance headache, that discipline translates directly into fewer write-offs and happier retail partners.\n\nBeing forklift trained isn't just a certification on paper for me — it means I can step onto the floor during peak loads, cover gaps without waiting on a scheduling fix, and see firsthand where bottlenecks actually happen rather than relying on secondhand reports. That's the kind of visibility an operations supervisor needs to make decisions that hold up under pressure, especially with perishable inventory and tight turnaround times.\n\nI'm ready to move from leading a shift to owning outcomes across your operation — reducing shrink, tightening pick accuracy further, and building a team culture where errors get caught before they become costly.
