The short version.

Charlie Duffell

I am an engineering student at NC State, minoring in business administration. Before college I worked front of house at a Chick-fil-A and kept watching the same part fail, so I designed a replacement, had it CNC manufactured, and started selling it.

That turned into Charlie's Innovations, which I ran as founding president from 2024 to 2026. It went from one product to three and reached ten operators. It also taught me the half of engineering that does not happen in CAD: pitching to people who did not ask for your idea, pricing it, and finding out what survives a full shift.

What I want next is automation, specifically the mechanical side of fulfillment and material handling. I have not worked in it professionally yet, so I am working toward it in the open. I am designing an adaptive dispensing system and writing about where the economics of fulfillment point.

Compared robotic-arm picking, A-frame dispensing, and cube storage, and argued dispensing scales cheaper, with replenishment as the next bottleneck.
