01AI Workflow · MHCI Capstone
CMU MHCI capstone with Goodwill of Southwestern Pennsylvania: its 32-store softlines business generates about $23.66M in annual sales. I turned warehouse research into Goodwill's first internal AI workflow tool: processors speak a garment's attributes and the agent drives the existing tagging software to print the label, lifting processor productivity by 123% in the pilot test and sell-through per processor by 15% on average.

Five people, one booked table, participants revealed only after the event, designed across iOS, Android, Apple Watch and a web entry point.
