How I operate

The architect who makes the whole system cohere

01

Architect across pillars

Floating between product, engineering, and design orgs to own the system, not a swimlane.

Proof: Facebook Design System
02

Zero to one, in the lab

Ambiguous brief to shipped product on a lean loop, with the PM and engineering fluency to keep the roadmap real.

Proof: Inworld AI
03

Design systems as infrastructure

Tokenized, themeable, governed. Systems that engineering adopts because they make shipping faster.

Proof: Pegasus
