About me
EFFYYANG
Product Manager & UX Designer
Product person who started in design and followed the problem upstream. I make order out of chaos — turning messy, repetitive manual work into systems people actually use (one now runs 24 care facilities), and getting teams that disagree into the same room to ship.
Based in Taiwan.
