01 About
Engineer.
Designer. Builder.
I’m Chen, an Apple-platform engineer in Seattle. I make focused products that respect the platform, the person using them, and the details most people never see.
Start a conversation02 The work
I like the point where
systems become feeling.
My work spans SwiftUI, watchOS, HealthKit, CloudKit, on-device AI, and the infrastructure that keeps an app reliable beyond its happy path.
I care about the whole product: naming and data flow, the motion of a transition, privacy boundaries, App Store delivery, and the small decisions that make software feel inevitable rather than assembled.
03 Principles
A few quiet
convictions.
Constraints I return to when architecture or product direction gets noisy.
- 01
Native by nature
Platform conventions are a creative constraint, not something to route around.
- 02
Private by default
On-device intelligence when possible, with clear boundaries when a service is needed.
- 03
Details are the product
The interface, edge cases, and invisible engineering all shape the experience.
04 Beyond Xcode
A wider field
of view.
Away from product work, I’m usually photographing a city, testing a training idea, or finding a better tool for an everyday ritual.
