Hello
I'm Paul, but I go by Stammy
On safari in Tanzania
I'm a designer who loves to code. I'm a huge advocate for having a high product quality bar and know that having an intimate understanding of technical constraints is a core part of elevating quality.
I'm the Head of Design at Sesame, where I focus on building voice-first personal intelligence. Previously, I was Co-Founder and Head of Design at Limitless (née Rewind AI), which was acquired by Meta. I also spent 9 years at Twitter, where I designed media and creation experiences, such as threads, camera, and composer.
I'm 40.282837062 years old and live in San Francisco with my wife Katherine, but previously lived in New York, Atlanta, and Houston. Photography is one of my hobbies. I designed and built elaborate photosets of my travels: Africa, New Zealand, Amsterdam, Japan, and more. I often share photos on my photostream.

I mainly use Twitter, where I like to talk about design, code and just generally things that interest me. I'm Stammy on most sites. That's been my nickname for years now. It's easier to say than my last name.

I've been publishing here since 2005 when I hosted it on a G4 Mac Mini in my dorm. Everything is designed and coded myself—no themes or templates here—in San Francisco on my MacBook Pro with the Glove80 keyboard and Pro Display XDR Display with the Cursor code editor, Ghostty terminal, and Arc browser.
- Built with TanStack Start (I used Next.js before), hosted on
VercelCloudflare workers with everything behind the Cloudflare proxy. Media is stored on Cloudflare R2 with most photos going through Cloudflare Image Transformations. - Uses Framer Motion, Tailwind CSS with some modified Shadcn components, as well as various custom components (such as photosets, the animated image filter at the top of this page, or components inside posts like Stocketa).
- I'm always exploring various typefaces, but currently use the following: Pangram Fragment Glare, Carrara by Hoftype, Averta by TDF, Source Sans 3, Argent Pixel by CF, and
Server MonoGeist Mono. All fonts have had glyphs manually subset to reduce file size. - Header tab icons custom made then animated myself using Lottie.
