Product designer with a founder's instinct

15+ years turning research and experiments into products that ship, at Microsoft, SigFig, Hagerty, and early-stage startups. Now designing and building with AI, working remotely from Korea with US teams, with at least four hours of overlap with the US workday.

How I work

Four habits I keep coming back to, each one from a project above.

Find the real problem first

When a request lands, I ask what it's for. At Hagerty I answered business asks with the why and a better option.

Let experiments decide

I’d rather ship a small test this week than argue about a big launch for a year. At Outlook, that became how the team worked.

Prototype to get everyone aligned

A clickable prototype settles debates a spec can't. At SigFig, sales tested ideas with clients before we built them.

Build with AI, judge like a designer

I set the rules and standards, Claude writes the code, and I check every result against real data.

My path so far

I started by building my own thing, spent years in agencies and big product teams, and keep coming back to founding work.

What people say
“Product” in “product designer” for him is not ceremonial. His skillset is more akin to a founder. … When he goes deep he goes insanely deep. When he goes broad he brings everyone along.
Philipp CannonsHead of Emerging Products, SigFig
Not only is he an incredibly skilled visual designer with an extremely refined eye, he is also very, very fast. … If you can hire him on full-time, you should.
Steve FarrellChief Creative Officer, SMITH
Working with Tony taught me how deep Design can go. He always brought conversations back to the problem space.
Brad RoganDirector of Engineering, SigFig
He drives design from user needs and real data first. … This level of product focus from design is rare to find.
Praneet WadgeSr. Product Manager, Superformula
Tony is self-driven, fearless and highly engaged.
Britta BurlinPrincipal Design Manager, Microsoft
He is always thinking about the bigger picture of a product and why it should even exist.
Nick BoesDesign Director, Superformula
His design smarts and speed were brilliant. He was a great team player who totally gets “World Class” design.

Outside of work

The things I come back to when I'm not designing.

My dog, my walking buddy, and the reason I step away from the screen every day.

Let’s talk

I'm looking for a remote senior, principal, or founding designer role on a product I can own end to end.
