About
I help crews spec, stage, and maintain cooler fleets that survive heat, transport, and rough handling. I map cold failures to downtime and safety risks, then build redundant workflows—shade, pre-chill, separation, and assignments—so people stay safe and jobs stay on schedule.
Background
On a paving job in August, the crew cooler failed before lunch. Morale cratered, productivity followed. We rebuilt the workflow: pre-chill overnight, shade every unit, separate food and hydration, and assign a cooler chief. Next week, temps and uptime held steady. The only complaint was heavier lids—worth it.
Perspective
I favor rugged gear, redundancy, and lifecycle cost over low weight or fashion.
