Goodwill Agent Voice-First Tagging at the Rack

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.

Hive Five Group Meetups for Bumble BFF

Individual project in Advanced Interaction Design at CMU: a brief for “nearby like” notifications became a group-meetup product after the course dataset showed friends mode converting best. Five people, one booked table, participants revealed only after the event, designed across iOS, Android, Apple Watch and a web entry point.

CMU team project: a three-wheel electric moped with physical controls and a digital dashboard for a rider with limited mobility. Usability testing with 6 participants reshaped how she switches between manual and auto mode, gets help in an emergency, and takes back control when the vehicle can’t handle a situation.
