E-Commerce Achievement Badge System

Roy Lo / 2012

Gamification System for Yahoo! E-Commerce

To boost seller engagement and loyalty, I co-designed the E-Commerce Achievement Badge System, a modular gamification layer for Yahoo’s marketplace. It rewarded users based on performance, behavior, and milestones, turning selling into a more motivating, game-like experience.

Key Highlights

  • Won Best EC Hack at Yahoo! Taiwan 2012 Internal Hackday

  • Designed a flexible badge system rewarding milestones like sales volume, ratings, and customer service

  • Created backend logic and frontend display modules for dynamic badge rendering

This project combined my UX, product thinking, and engineering skills to create behavioral impact through smart incentives.
