01 About

I'm Hsuan, a founder and software engineer based in Taipei. I co-founded Blocto (portto) and led it as CEO from 2019 to 2025, making blockchain apps simple enough for anyone to use. Before that I led engineering at COBINHOOD and DEXON, and built web apps at 17 Media, Agoda and Yahoo. Away from the keyboard, I travel and take photos.
