Goodwill Agent Voice-first tagging at the rack

CMU MHCI capstone with Goodwill of Southwestern Pennsylvania, whose 32-store softlines business brings in about $23.66M in annual sales. Starting from warehouse research, I built Goodwill’s first internal AI workflow tool. Processors say a garment’s attributes, and the agent operates the existing tagging software for them to print the label. In a one-week in-store pilot, a processor went from about 39 to about 83 soft-line items an hour, a 112% increase.

Hive Five Group meetups for Bumble BFF

Individual project in Advanced Interaction Design at CMU. The brief was originally to design “nearby like” notifications. The course data showed BFF, Bumble’s friends mode, converting best, so I turned it into group meetups: five people per event, a table booked in advance, and participants revealed only after the event. The design covers iOS, Android, Apple Watch and a web entry point.

CMU team project. We designed a semi-autonomous three-wheel electric moped for a rider with limited mobility, including its physical controls and digital dashboard. Based on usability testing with 6 participants, we redesigned three moments: how she switches between manual and auto mode, how she gets help in an emergency, and how control goes back to her when the vehicle can’t handle a situation.

The auto-mode dashboard: a 3D view from behind the moped, a speed dial at 30 mph, and the prompt Vehicle ahead, maintaining distance
