About

Product Designer, Leader, and Builder

Hey, I'm Sean, a product designer with 16+ years of experience.

I'm looking to build with a great team of humans and agents. Ages ago, I was the founding designer at MileIQ (acq. Microsoft), then 10 years at Microsoft where I led a team of 11 for Outlook Mobile and Mac. I make things with my hands and with agents, including apps I've shipped solo like Brukas and Ghostties, with more to come.

I live north of San Francisco with my wife, our two daughters, four and one, and our dog.

Let's make something together!

Looking for full-time design leadership, and open to advisory. Email is fastest, I read every one.

How I Work Now

People have been asking what my day-to-day looks like now: friends, some teams I've been talking to. This is a start to that answer. I'm a designer. My practice has shifted substantially in the last six months. For me, Claude Code is at the center of what I'm doing every single day. I love visual tools, but I spend most of my day in a terminal now. The canvas is where I go when the craft demands it.

With my hands

You keep learning and trying things till you really have to hire someone. I remodeled the whole house that way: kitchen, floors, two bathrooms, a Murphy bed I designed in Shapr3D and built by hand.

What I build with

“The kit stays small. The bias to ship stays high.”

Design: Paper.design, Pencil.dev, Figma, Claude Design · Build: Claude Code, Cursor, React, Next.js, Tailwind, Xcode, GitHub · Run: Supabase, Vercel, Ghostties, Linear, Obsidian · Own: self-built tools and skills

What if?

Always curious how things work, and how I work keeps changing, so I build to find out. My own iOS app, a multi-agent terminal, small experiments. I have my gaps. I learn until I'm past them.

Ghostties

A native macOS terminal with a sidebar of agent sessions, so you can see what's running and what needs you at a glance. It's an open-source fork of Ghostty, the fast native terminal by Mitchell Hashimoto, with a SwiftUI sidebar for running agents in parallel. Free to try.

Home base

Two daughters, 1 and 4, my wife, and Carmela our shepherd mix. Petaluma: playgrounds, drawing, oysters in Tomales Bay. Quiet, with the city and wine country close.
