About

I’m Sean, a senior product designer at Meta in Seattle, owning the lower funnel for shopping across Instagram and Facebook Shops.

For eight years I’ve gravitated toward the same kind of problem: complex, high-stakes surfaces where millions of people are trying to get something done — checking out, joining a call, finding their next game. The craft I care about is making those moments feel clear and transparent, making each surface incrementally better.

Outside of work I like to hike, ride my motorcycle, and build slightly too many Legos.

How I Work

/01

AI-native

We’re in a new age where AI can help me prototype quicker, explore multiple concepts faster and pitch to partners more efficiently. Becoming AI native has meant I’m able to get involved in 3x as many projects as before with better results and clearer communication.

/02

Prototype the argument

Working software is more persuasive than a deck. I frame problems with Claude, build real prototypes in Cursor and Claude Code on production components, and use Figma for systems and polish.

/03

Own it end to end

The best projects I’ve shipped have been pitches from myself or in tight collaboration with product from the beginning. Scope is something I’ve learned to find, not something you’re given.
