ABOUT

About Niney.

"I'm Niney, a ToC product manager with 3+ years building at the intersection of AI and healthcare."

My background is a bit 'mixed' — and that's exactly what I value most. A cross-domain lens lets me read the emotion behind the numbers and find leverage points inside heavy industry constraints.

I believe great products aren't feature piles — they solve real pain at the right moment with the lightest touch. In healthcare, where trust is the highest barrier, I learned to walk the tightrope between compliance and experience, and to respect the user's fear as much as their hope.

These days I'm watching chronic-disease care and patient education, with side curiosity about consumer health and B2C medical services.

What I believe

  1. / 01

    Users don't lie, but they mislead you

    Real needs hide in behavior — not in interviews.

  2. / 02

    Crossing fields is resolution, not a deficit

    Having seen other industries, you know which 'conventions' deserve to be broken.

  3. / 03

    First duty of a healthcare product: do no harm

    Decide where the boundary is — before chasing growth.

  4. / 04

    Good product docs are a form of respect

    For engineers, designers, and your future self.
