Apple-platform engineer · Seattle

Software, with feeling.

I’m Chen. I design and build focused apps for the Apple ecosystem— native, private, and considered down to the last interaction.

02 / How I work

Built on a few
quiet convictions.

  1. 01

    Native by nature

    Platform conventions are a creative constraint, not something to route around.

  2. 02

    Private by default

    On-device intelligence when possible. No analytics, trackers, or attention traps.

  3. 03

    Details are the product

    The interface, the edge cases, and the invisible engineering all shape the feeling.

04 / About

Engineer.
Designer.
Builder.

I’m an Apple-platform engineer based in Seattle. I work across SwiftUI, watchOS, HealthKit, CloudKit, on-device AI, and the systems that make products reliable beyond the happy path.

Away from Xcode, I’m usually photographing a city, trying a new training block, or finding a better tool for an everyday ritual.
