"ReturnRing team on AMD Developer Hackathon: ACT III Hackathon"

Team Idea

ReturnRing tells a wrong size from a ring of linked accounts: models score risk, rules stay within EU law, Gemma 4 on AMD explains, a person approves. A return decision assistant for EU fashion e-commerce: the 14-day withdrawal is never denied and restrictions apply only to future orders. Gemma 4 runs on AMD Token Factory; the XGBoost and GraphSAGE models were trained on an AMD Instinct MI300X. Live demo: returnring-demo-production.up.railway.app Who we need: an EU fashion merchant for a two-phase pilot (observe first, then a controlled test), a returns or customer-care manager to tell us which cases are hardest, and a consumer-law professional to review the levers. Solo builder: Rosario Barbagallo.
