Jiyoung Jung
Product Manager
I’m a product manager at Perso AI, where I lead feature planning for Perso Dubbing — from dubbing workflows to lip sync. Before moving into product, I managed QA at ESTsoft, which shaped how I evaluate AI video tools: not by demos, but by how they hold up in production. I write about AI dubbing technology, product workflows, and what separates reliable AI video output from a good-looking sample.
