John Mackoy is a dependable inventory professional with over a decade of hands-on experience replenishing retail operations and optimizing customer-facing areas for major retailers like Walmart and The Home Depot. His background also includes early-career technical engineering and programming roles at firms such as Fidelity Investments and Dallas Systems Corporation, where he developed disaster recovery processes, system utilities, and database support—skills that give him a rare blend of logistical know-how and legacy technical expertise. Known for discretion and strong communication, he reliably handles sensitive information and coordinates teams and volunteers, from rebuilding homes after hurricanes to managing store floor operations. Comfortable with Microsoft Office and proprietary inventory systems, he pairs practical computer literacy with a collaborative, customer-focused approach. Based in Cedar Hill, Texas, he brings steady operational judgment and a curiosity-driven mindset (reflected in his GitHub bio) that helps him adapt technical lessons to real-world retail challenges.
