How I lead
Balanced autonomy
I give designers the freedom to own their work while staying close enough to unblock, redirect, and amplify their impact when it counts.
Radical transparency
I share context openly — the why behind decisions, the tradeoffs we're making, the things that are uncertain — so everyone can do their best work.
Open collaborations
Design doesn't happen in a silo. I build strong cross-functional partnerships and create space for every voice to shape the outcome.
Growth and joy
I invest in the people around me — their craft, their confidence, and their careers. And I try to make the work genuinely fun along the way.
